Class DocumentBase

Provides the abstract base class for a main document and a glossary document of a Word document.

Aspose.Words represents a Word document as a tree of nodes. DocumentBase is a root node of the tree that contains all other nodes of the document.

DocumentBase also stores document-wide information such as Styles and Lists that the tree nodes might refer to.

    • Property Getters/Setters Detail

      • getChildNodes

        public NodeCollection getChildNodes()
        
        Gets all immediate child nodes of this node.

        Note, ChildNodes is equivalent to calling GetChildNodes(NodeType.Any, false) and creates and returns a new collection every time it is accessed.

        If there are no child nodes, this property returns an empty collection.

        Example:

        Shows how to enumerate immediate children of a CompositeNode using the enumerator provided by the ChildNodes collection.
        NodeCollection children = paragraph.getChildNodes();
        for (Node child : (Iterable<Node>) children)
        {
            // Paragraph may contain children of various types such as runs, shapes and so on.
            if (child.getNodeType() == NodeType.RUN)
            {
                // Say we found the node that we want, do something useful.
                Run run = (Run) child;
                System.out.println(run.getText());
            }
        }
      • getCount

        public int getCount()
        
        Gets the number of immediate children of this node.
      • getDocument

        public DocumentBase getDocument()
        
        Gets the document to which this node belongs.

        The node always belongs to a document even if it has just been created and not yet added to the tree, or if it has been removed from the tree.

        Example:

        Shows that when you create any node, it requires a document that will own the node.
        // Open a file from disk.
        Document doc = new Document();
        
        // Creating a new node of any type requires a document passed into the constructor.
        Paragraph para = new Paragraph(doc);
        
        // The new paragraph node does not yet have a parent.
        System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));
        
        // But the paragraph node knows its document.
        System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));
        
        // The fact that a node always belongs to a document allows us to access and modify
        // properties that reference the document-wide data such as styles or lists.
        para.getParagraphFormat().setStyleName("Heading 1");
        
        // Now add the paragraph to the main text of the first section.
        doc.getFirstSection().getBody().appendChild(para);
        
        // The paragraph node is now a child of the Body node.
        System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));
      • getFirstChild

        public Node getFirstChild()
        
        Gets the first child of the node. If there is no first child node, a null is returned.

        Example:

        Shows how to enumerate immediate child nodes of a composite node using NextSibling. In this example we enumerate all paragraphs of a section body.
        // Get the section that we want to work on.
        Section section = doc.getSections().get(0);
        Body body = section.getBody();
        
        // Loop starting from the first child until we reach null.
        for (Node node = body.getFirstChild(); node != null; node = node.getNextSibling())
        {
            // Output the types of the nodes that we come across.
            System.out.println(Node.nodeTypeToString(node.getNodeType()));
        }

        Example:

        Shows how to efficiently visit all direct and indirect children of a composite node.
        public void recurseAllNodes() throws Exception
        {
            // Open a document.
            Document doc = new Document(getMyDir() + "Node.RecurseAllNodes.doc");
        
            // Invoke the recursive function that will walk the tree.
            traverseAllNodes(doc);
        }
        
        /**
         * A simple function that will walk through all children of a specified node recursively
         * and print the type of each node to the screen.
         */
        public void traverseAllNodes(CompositeNode parentNode)
        {
            // This is the most efficient way to loop through immediate children of a node.
            for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling())
            {
                // Do some useful work.
                System.out.println(Node.nodeTypeToString(childNode.getNodeType()));
        
                // Recurse into the node if it is a composite node.
                if (childNode.isComposite()) traverseAllNodes((CompositeNode) childNode);
            }
        }
      • getFontInfos

        public FontInfoCollection getFontInfos()
        
        Provides access to properties of fonts used in this document.

        This collection of font definitions is loaded as is from the document. Font definitions might be optional, missing or incomplete in some documents.

        Do not rely on this collection to ascertain that a particular font is used in the document. You should only use this collection to get information about fonts that might be used in the document.

        Example:

        Shows how to save a document with embedded TrueType fonts
        Document doc = new Document(getMyDir() + "Document.docx");
        
        FontInfoCollection fontInfos = doc.getFontInfos();
        fontInfos.setEmbedTrueTypeFonts(true);
        fontInfos.setEmbedSystemFonts(false);
        fontInfos.setSaveSubsetFonts(false);
        
        doc.save(getMyDir() + "/Artifacts/Document.docx");

        Example:

        Shows how to gather the details of what fonts are present in a document.
        Document doc = new Document(getMyDir() + "Document.doc");
        
        FontInfoCollection fonts = doc.getFontInfos();
        int fontIndex = 1;
        
        // The fonts info extracted from this document does not necessarily mean that the fonts themselves are
        // used in the document. If a font is present but not used then most likely they were referenced at some time
        // and then removed from the Document.
        for (FontInfo info : fonts)
        {
            // Print out some important details about the font.
            System.out.println(MessageFormat.format("Font #{0}", fontIndex));
            System.out.println(MessageFormat.format("Name: {0}", info.getName()));
            System.out.println(MessageFormat.format("IsTrueType: {0}", info.isTrueType()));
            fontIndex++;
        }

      • hasChildNodes

        public boolean hasChildNodes()
        
        Returns true if this node has any child nodes.

        Example:

        Demonstrates how to use the InsertDocument method to insert a document into a merge field during mail merge.
        public void insertDocumentAtMailMerge() throws Exception
        {
            // Open the main document.
            Document mainDoc = new Document(getMyDir() + "InsertDocument1.doc");

        }
      • isComposite

        public boolean isComposite()
        
        Returns true as this node can have child nodes.

        Example:

        Shows how to efficiently visit all direct and indirect children of a composite node.
        public void recurseAllNodes() throws Exception
        {

            traverseAllNodes(doc);
        }
        
        /**
         * A simple function that will walk through all children of a specified node recursively
         * and print the type of each node to the screen.
         */
        public void traverseAllNodes(CompositeNode parentNode)
        {

        }
      • getLastChild

        public Node getLastChild()
        
        Gets the last child of the node. If there is no last child node, a null is returned.

        Example:

        Demonstrates use of methods of Node and CompositeNode to remove a section before the last section in the document.
        // Document is a CompositeNode and LastChild returns the last child node in the Document node.
        // Since the Document can contain only Section nodes, the last child is the last section.
        Node lastSection = doc.getLastChild();
        
        // Each node knows its next and previous sibling nodes.
        // Previous sibling of a section is a section before the specified section.
        // If the node is the first child, PreviousSibling will return null.
        Node sectionBeforeLast = lastSection.getPreviousSibling();

        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        // Create a numbered list based on one of the Microsoft Word list templates and
        // apply it to the current paragraph in the document builder.

      • getNodeType

        public abstract int getNodeType()
        
        Gets the type of this node. The value of the property is NodeType integer constant.

        Example:

        Shows how to enumerate immediate child nodes of a composite node using NextSibling. In this example we enumerate all paragraphs of a section body.
        // Get the section that we want to work on.
        Section section = doc.getSections().get(0);
        Body body = section.getBody();
        
        // Loop starting from the first child until we reach null.
        for (Node node = body.getFirstChild(); node != null; node = node.getNextSibling())
        {
            // Output the types of the nodes that we come across.
            System.out.println(Node.nodeTypeToString(node.getNodeType()));
        }

        Example:

        Shows how to remove all nodes of a specific type from a composite node. In this example we remove tables from a section body.
        // Get the section that we want to work on.
        Section section = doc.getSections().get(0);
        Body body = section.getBody();
        
        // Select the first child node in the body.
        Node curNode = body.getFirstChild();
        
        while (curNode != null)
        {
            // Save the pointer to the next sibling node because if the current
            // node is removed from the parent in the next step, we will have
            // no way of finding the next node to continue the loop.
            Node nextNode = curNode.getNextSibling();
        
            // A section body can contain Paragraph and Table nodes.
            // If the node is a Table, remove it from the parent.
            if (curNode.getNodeType() == NodeType.TABLE) curNode.remove();
        
            // Continue going through child nodes until null (no more siblings) is reached.
            curNode = nextNode;
        }

        Example:

        Shows how to retrieve the NodeType enumeration of nodes.
        Document doc = new Document(getMyDir() + "Document.doc");
        
        // Let's pick a node that we can't be quite sure of what type it is.
        // In this case lets pick the first node of the first paragraph in the body of the document
        Node node = doc.getFirstSection().getBody().getFirstParagraph().getFirstChild();
        System.out.println("NodeType of first child: " + Node.nodeTypeToString(node.getNodeType()));
        
        // This time let's pick a node that we know the type of. Create a new paragraph and a table node.
        Paragraph para = new Paragraph(doc);
        Table table = new Table(doc);
        
        // Access to NodeType for typed nodes will always return their specific NodeType.
        // i.e A paragraph node will always return NodeType.Paragraph, a table node will always return NodeType.Table.
        System.out.println("NodeType of Paragraph: " + Node.nodeTypeToString(para.getNodeType()));
        System.out.println("NodeType of Table: " + Node.nodeTypeToString(table.getNodeType()));
      • getPageColor/setPageColor

        public java.awt.Color getPageColor() / public void setPageColor(java.awt.Color value)
        
        Gets or sets the page color of the document. This property is a simpler version of BackgroundShape.

        This property provides a simple way to specify a solid page color for the document. Setting this property creates and sets an appropriate BackgroundShape.

        If the page color is not set (e.g. there is no background shape in the document) returns a zero color.

        See Also:
        BackgroundShape
      • getParentNode

        public CompositeNode getParentNode()
        
        Gets the immediate parent of this node.

        If a node has just been created and not yet added to the tree, or if it has been removed from the tree, the parent is null.

        Example:

        Shows how to access the parent node.
        // Create a new empty document. It has one section.
        Document doc = new Document();
        
        // The section is the first child node of the document.
        Node section = doc.getFirstChild();
        
        // The section's parent node is the document.
        System.out.println("Section parent is the document: " + (doc == section.getParentNode()));

        Example:

        Shows that when you create any node, it requires a document that will own the node.
        // Open a file from disk.
        Document doc = new Document();
        
        // Creating a new node of any type requires a document passed into the constructor.
        Paragraph para = new Paragraph(doc);
        
        // The new paragraph node does not yet have a parent.
        System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));
        
        // But the paragraph node knows its document.
        System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));
        
        // The fact that a node always belongs to a document allows us to access and modify
        // properties that reference the document-wide data such as styles or lists.
        para.getParagraphFormat().setStyleName("Heading 1");
        
        // Now add the paragraph to the main text of the first section.
        doc.getFirstSection().getBody().appendChild(para);
        
        // The paragraph node is now a child of the Body node.
        System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));
      • getPreviousSibling

        public Node getPreviousSibling()
        
        Gets the node immediately preceding this node. If there is no preceding node, a null is returned.

        Example:

        Demonstrates use of methods of Node and CompositeNode to remove a section before the last section in the document.
        // Document is a CompositeNode and LastChild returns the last child node in the Document node.
        // Since the Document can contain only Section nodes, the last child is the last section.
        Node lastSection = doc.getLastChild();
        
        // Each node knows its next and previous sibling nodes.
        // Previous sibling of a section is a section before the specified section.
        // If the node is the first child, PreviousSibling will return null.
        Node sectionBeforeLast = lastSection.getPreviousSibling();
        
        if (sectionBeforeLast != null) doc.removeChild(sectionBeforeLast);
      • getRange

        public Range getRange()
        
        Returns a Range object that represents the portion of a document that is contained in this node.

        Example:

        Shows how to delete all characters of a range.
        // Open Word document.
        Document doc = new Document(getMyDir() + "Range.DeleteSection.doc");
        
        // The document contains two sections. Each section has a paragraph of text.
        System.out.println(doc.getText());
        
        // Delete the first section from the document.
        doc.getSections().get(0).getRange().delete();
        
        // Check the first section was deleted by looking at the text of the whole document again.
        System.out.println(doc.getText());
      • getResourceLoadingCallback/setResourceLoadingCallback

        public IResourceLoadingCallback getResourceLoadingCallback() / public void setResourceLoadingCallback(IResourceLoadingCallback value)
        
        Allows to control how external resources are loaded.
      • getStyles

        public StyleCollection getStyles()
        
        Returns a collection of styles defined in the document.

        For more information see the description of the StyleCollection class.

        Example:

        Shows how to get access to the collection of styles defined in the document.
        Document doc = new Document();
        StyleCollection styles = doc.getStyles();
        
        for (Style style : styles)
            System.out.println(style.getName());

        Example:

        Shows how to create and use a paragraph style with list formatting.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        // Create a paragraph style and specify some formatting for it.
        Style style = doc.getStyles().add(StyleType.PARAGRAPH, "MyStyle1");
        style.getFont().setSize(24);
        style.getFont().setName("Verdana");
        style.getParagraphFormat().setSpaceAfter(12);
        
        // Create a list and make sure the paragraphs that use this style will use this list.
        style.getListFormat().setList(doc.getLists().add(ListTemplate.BULLET_DEFAULT));
        style.getListFormat().setListLevelNumber(0);
        
        // Apply the paragraph style to the current paragraph in the document and add some text.
        builder.getParagraphFormat().setStyle(style);
        builder.writeln("Hello World: MyStyle1, bulleted.");
        
        // Change to a paragraph style that has no list formatting.
        builder.getParagraphFormat().setStyle(doc.getStyles().get("Normal"));
        builder.writeln("Hello World: Normal.");
        
        builder.getDocument().save(getMyDir() + "\\Artifacts\\Lists.ParagraphStyleBulleted.doc");

      • getWarningCallback/setWarningCallback

        public IWarningCallback getWarningCallback() / public void setWarningCallback(IWarningCallback value)
        
        Called during various document processing procedures when an issue is detected that might result in data or formatting fidelity loss. Document may generate warnings at any stage of its existence, so it's important to setup warning callback as early as possible to avoid the warnings loss. E.g. such properties as Document.PageCount actually build the document layout which is used later for rendering, and the layout warnings may be lost if warning callback is specified just for the rendering calls later.

        Example:

        Demonstrates how to implement the IWarningCallback to be notified of any font substitution during document save.
        public static class HandleDocumentWarnings implements IWarningCallback
        {
            /**
             *  Our callback only needs to implement the "Warning" method. This method is called whenever there is a
             *  potential issue during document processing. The callback can be set to listen for warnings generated during document
             *  load and/or document save.
             */
            public void warning(WarningInfo info)
            {
                // We are only interested in fonts being substituted.
                if (info.getWarningType() == WarningType.FONT_SUBSTITUTION)
                {
                    System.out.println("Font substitution: " + info.getDescription());
                }
            }
        
        }

        Example:

        Demonstrates how to receive notifications of font substitutions by using IWarningCallback.
        // Load the document to render.
        Document doc = new Document(getMyDir() + "Document.doc");
        
        // Create a new class implementing IWarningCallback and assign it to the PdfSaveOptions class.
        HandleDocumentWarnings callback = new HandleDocumentWarnings();
        doc.setWarningCallback(callback);
        
        // We can choose the default font to use in the case of any missing fonts.
        FontSettings.getDefaultInstance().setDefaultFontName("Arial");
        
        // For testing we will set Aspose.Words to look for fonts only in a folder which doesn't exist. Since Aspose.Words won't
        // find any fonts in the specified directory, then during rendering the fonts in the document will be substituted with the default 
        // font specified under FontSettings.DefaultFontName. We can pick up on this substitution using our callback.
        FontSettings.getDefaultInstance().setFontsFolder("", false);
        
        // Pass the save options along with the save path to the save method.
        doc.save(getMyDir() + "\\Artifacts\\Rendering.MissingFontNotification.pdf");

      • accept

        public abstract boolean accept(DocumentVisitor visitor)
                                    throws java.lang.Exception
        Accepts a visitor.

        Enumerates over this node and all of its children. Each node calls a corresponding method on DocumentVisitor.

        For more info see the Visitor design pattern.

        Parameters:
        visitor - The visitor that will visit the nodes.
        Returns:
        True if all nodes were visited; false if DocumentVisitor stopped the operation before visiting all nodes.

        Example:

        Implements the Visitor Pattern to remove all content formatted as hidden from the document.
        public void removeHiddenContentFromDocument() throws Exception

      • appendChild

        public Node appendChild(Node newChild)
        Adds the specified node to the end of the list of child nodes for this node.

        If the newChild is already in the tree, it is first removed.

        If the node being inserted was created from another document, you should use importNode(com.aspose.words.Node,boolean,int) to import the node to the current document. The imported node can then be inserted into the current document.

        Parameters:
        newChild - The node to add.
        Returns:
        The node added.

        Example:

        Creates a simple document from scratch using the Aspose.Words object model.
        // Create an "empty" document. Note that like in Microsoft Word,
        // the empty document has one section, body and one paragraph in it.
        Document doc = new Document();
        
        // This truly makes the document empty. No sections (not possible in Microsoft Word).
        doc.removeAllChildren();
        
        // Create a new section node.
        // Note that the section has not yet been added to the document,
        // but we have to specify the parent document.
        Section section = new Section(doc);
        
        // Append the section to the document.
        doc.appendChild(section);
        
        // Lets set some properties for the section.
        section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
        section.getPageSetup().setPaperSize(PaperSize.LETTER);
        
        // The section that we created is empty, lets populate it. The section needs at least the Body node.
        Body body = new Body(doc);
        section.appendChild(body);
        
        // The body needs to have at least one paragraph.
        // Note that the paragraph has not yet been added to the document,
        // but we have to specify the parent document.
        // The parent document is needed so the paragraph can correctly work
        // with styles and other document-wide information.
        Paragraph para = new Paragraph(doc);
        body.appendChild(para);
        
        // We can set some formatting for the paragraph
        para.getParagraphFormat().setStyleName("Heading 1");
        para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);
        
        // So far we have one empty paragraph in the document.
        // The document is valid and can be saved, but lets add some text before saving.
        // Create a new run of text and add it to our paragraph.
        Run run = new Run(doc);
        run.setText("Hello World!");
        run.getFont().setColor(Color.RED);
        para.appendChild(run);
        
        // As a matter of interest, you can retrieve text of the whole document and
        // see that \x000c is automatically appended. \x000c is the end of section character.
        System.out.println(doc.getText());
        
        // Save the document.
        doc.save(getMyDir() + "\\Artifacts\\Section.CreateFromScratch.doc");
      • deepClone

        public Node deepClone(boolean isCloneChildren)

        Example:

        Shows how to clone composite nodes with and without their child nodes.
        // Create a new empty document.
        Document doc = new Document();
        
        // Add some text to the first paragraph
        Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();
        para.appendChild(new Run(doc, "Some text"));
        
        // Clone the paragraph and the child nodes.
        Node cloneWithChildren = para.deepClone(true);
        // Only clone the paragraph and no child nodes.
        Node cloneWithoutChildren = para.deepClone(false);
      • getAncestor

        public CompositeNode getAncestor(int ancestorType)
        Gets the first ancestor of the specified NodeType.
        Parameters:
        ancestorType - A NodeType value. The node type of the ancestor to retrieve.
        Returns:
        The ancestor of the specified type or null if no ancestor of this type was found.

        Example:

      • getAncestor

        public CompositeNode getAncestor(java.lang.Class ancestorType)
        Gets the first ancestor of the specified object type.

        The ancestor type matches if it is equal to ancestorType or derived from ancestorType.

        Parameters:
        ancestorType - The object type of the ancestor to retrieve.
        Returns:
        The ancestor of the specified type or null if no ancestor of this type was found.
      • getChild

        public Node getChild(int nodeType, int index, boolean isDeep)
        Returns an Nth child node that matches the specified type.

        If index is out of range, a null is returned.

        Note that markup nodes (NodeType.STRUCTURED_DOCUMENT_TAG and NodeType.SMART_TAG) are traversed even when isDeep = false and GetChild is invoked for non-markup node type. For example if the first run in a para is wrapped in a StructuredDocumentTag, it will still be returned by GetChild(NodeType.Run, 0, false).
        Parameters:
        nodeType - A NodeType value. Specifies the type of the child node.
        index - Zero based index of the child node to select. Negative indexes are also allowed and indicate access from the end, that is -1 means the last node.
        isDeep - True to select from all child nodes recursively. False to select only among immediate children. See remarks for more info.
        Returns:
        The child node that matches the criteria or null if no matching node is found.

        Example:

        Shows how to test if a node is inside a field by using an XPath expression.
        // Let's pick a document we know has some fields in.
        Document doc = new Document(getMyDir() + "MailMerge.MergeImage.doc");
        
        // Let's say we want to check if the Run below is inside a field.
        Run run = (Run) doc.getChild(NodeType.RUN, 5, true);
        
        // Evaluate the XPath expression. The resulting NodeList will contain all nodes found inside a field a field (between FieldStart
        // and FieldEnd exclusive). There can however be FieldStart and FieldEnd nodes in the list if there are nested fields
        // in the path. Currently does not find rare fields in which the FieldCode or FieldResult spans across multiple paragraphs.
        NodeList resultList = doc.selectNodes("//FieldStart/following-sibling::node()[following-sibling::FieldEnd]");
        
        // Check if the specified run is one of the nodes that are inside the field.
        for (Node node : (Iterable<Node>) resultList)
        {
            if (node == run)
            {
                System.out.println("The node is found inside a field");
                break;
            }
        }

        Example:

        Shows how to extract a specific child node from a CompositeNode by using the GetChild method and passing the NodeType and index.
        Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
      • getChildNodes

        public NodeCollection getChildNodes(int nodeType, boolean isDeep)
        Returns a live collection of child nodes that match the specified type.

        The collection of nodes returned by this method is always live.

        A live collection is always in sync with the document. For example, if you selected all sections in a document and enumerate through the collection deleting the sections, the section is removed from the collection immediately when it is removed from the document.

        Parameters:
        nodeType - A NodeType value. Specifies the type of nodes to select.
        isDeep - True to select from all child nodes recursively. False to select only among immediate children.
        Returns:
        A live collection of child nodes of the specified type.

        Example:

        Shows how to extract images from a document and save them as files.
        public void extractImagesToFiles() throws Exception
        {
            Document doc = new Document(getMyDir() + "Image.SampleImages.doc");
        
            NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);
            int imageIndex = 0;
            for (Shape shape : (Iterable<Shape>) shapes)
            {
                if (shape.hasImage())
                {
                    String imageFileName = java.text.MessageFormat.format("\\Artifacts\\Image.ExportImages.{0} Out{1}", imageIndex, FileFormatUtil.imageTypeToExtension(shape.getImageData().getImageType()));
                    shape.getImageData().save(getMyDir() + imageFileName);
                    imageIndex++;
                }
            }
        }

        Example:

        Demonstrates how to remove a specified TOC from a document.
        public void removeTOCFromDocument() throws Exception
        {
            // Open a document which contains a TOC.
            Document doc = new Document(getMyDir() + "Document.TableOfContents.doc");
        
            // Remove the first TOC from the document.
            Field tocField = doc.getRange().getFields().get(0);
            tocField.remove();
        
            // Save the output.
            doc.save(getMyDir() + "\\Artifacts\\Document.TableOfContentsRemoveTOC.doc");
        }
      • getText

        public java.lang.String getText()
        Gets the text of this node and of all its children.

        The returned string includes all control and special characters as described in ControlChar.

        Example:

        Shows the difference between calling the GetText and ToString methods on a node.
        Document doc = new Document();
        
        // Enter a dummy field into the document.
        DocumentBuilder builder = new DocumentBuilder(doc);
        builder.insertField("MERGEFIELD Field");
        
        // GetText will retrieve all field codes and special characters
        System.out.println("GetText() Result: " + doc.getText());
        
        // ToString will export the node to the specified format. When converted to text it will not retrieve fields code
        // or special characters, but will still contain some natural formatting characters such as paragraph markers etc.
        // This is the same as "viewing" the document as if it was opened in a text editor.
        System.out.println("ToString() Result: " + doc.toString(SaveFormat.TEXT));

        Example:

        Finds and outputs all paragraphs in a document that are bulleted or numbered.
        NodeCollection paras = doc.getChildNodes(NodeType.PARAGRAPH, true);
        for (Paragraph para : (Iterable<Paragraph>) paras)
        {
            if (para.getListFormat().isListItem())
            {
                System.out.println(java.text.MessageFormat.format("*** A paragraph belongs to list {0}", para.getListFormat().getList().getListId()));
                System.out.println(para.getText());
            }
        }
      • importNode

        public Node importNode(Node srcNode, boolean isImportChildren)

        Imports a node from another document to the current document.

        This method uses the ImportFormatMode.USE_DESTINATION_STYLES option to resolve formatting.

        Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.

        Before a node from another document can be inserted into this document, it must be imported. During import, document-specific properties such as references to styles and lists are translated from the original to the importing document. After the node was imported, it can be inserted into the appropriate place in the document using insertBefore(com.aspose.words.Node,com.aspose.words.Node) or insertAfter(com.aspose.words.Node,com.aspose.words.Node).

        If the source node already belongs to the destination document, then simply a deep clone of the source node is created.

        Parameters:
        srcNode - The node being imported.
        isImportChildren - True to import all child nodes recursively; otherwise, false.
        Returns:
        The cloned node that belongs to the current document.
        See Also:
        NodeImporter
      • importNode

        public Node importNode(Node srcNode, boolean isImportChildren, int importFormatMode)

        Imports a node from another document to the current document with an option to control formatting.

        This overload is useful to control how styles and list formatting are imported.

        Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.

        Before a node from another document can be inserted into this document, it must be imported. During import, document-specific properties such as references to styles and lists are translated from the original to the importing document. After the node was imported, it can be inserted into the appropriate place in the document using insertBefore(com.aspose.words.Node,com.aspose.words.Node) or insertAfter(com.aspose.words.Node,com.aspose.words.Node).

        If the source node already belongs to the destination document, then simply a deep clone of the source node is created.

        Parameters:
        srcNode - The node to imported.
        isImportChildren - True to import all child nodes recursively; otherwise, false.
        importFormatMode - A ImportFormatMode value. Specifies how to merge style formatting that clashes.
        Returns:
        The cloned, imported node. The node belongs to the destination document, but has no parent.
        See Also:
        ImportFormatMode, NodeImporter

        Example:

        Exports the content of a node to string in HTML format using custom specified options.
        Document doc = new Document(getMyDir() + "Document.doc");
        
        // Extract the last paragraph in the document to convert to HTML.
        Node node = doc.getLastSection().getBody().getLastParagraph();
        
        // Create an instance of HtmlSaveOptions and set a few options.
        HtmlSaveOptions saveOptions = new HtmlSaveOptions();
        saveOptions.setExportHeadersFootersMode(ExportHeadersFootersMode.PER_SECTION);
        saveOptions.setExportRelativeFontSize(true);
        
        // Convert the document to HTML and return as a string. Pass the instance of HtmlSaveOptions to
        // to use the specified options during the conversion.
        String nodeAsHtml = node.toString(saveOptions);
      • toString

        public java.lang.String toString(int saveFormat)
                       throws java.lang.Exception
        Exports the content of the node into a string in the specified format.
        Returns:
        The content of the node in the specified format.
        Parameters:
        saveFormat - A SaveFormat value.

        Example:

        Shows how to extract the label of each paragraph in a list as a value or a String.
        Document doc = new Document(getMyDir() + "Lists.PrintOutAllLists.doc");
        doc.updateListLabels();
        int listParaCount = 1;
        
        for (Paragraph paragraph : (Iterable<Paragraph>) doc.getChildNodes(NodeType.PARAGRAPH, true))
        {
            // Find if we have the paragraph list. In our document our list uses plain arabic numbers,
            // which start at three and ends at six.
            if (paragraph.getListFormat().isListItem())
            {
                System.out.println(MessageFormat.format("Paragraph #{0}", listParaCount));
        
                // This is the text we get when actually getting when we output this node to text format.
                // The list labels are not included in this text output. Trim any paragraph formatting characters.
                String paragraphText = paragraph.toString(SaveFormat.TEXT).trim();
                System.out.println("Exported Text: " + paragraphText);
        
                ListLabel label = paragraph.getListLabel();
                // This gets the position of the paragraph in current level of the list. If we have a list with multiple level then this
                // will tell us what position it is on that particular level.
                System.out.println("Numerical Id: " + label.getLabelValue());
        
                // Combine them together to include the list label with the text in the output.
                System.out.println("List label combined with text: " + label.getLabelString() + " " + paragraphText);
        
                listParaCount++;
            }
        }

        Example:

        Shows the difference between calling the GetText and ToString methods on a node.
        Document doc = new Document();
        
        // Enter a dummy field into the document.
        DocumentBuilder builder = new DocumentBuilder(doc);
        builder.insertField("MERGEFIELD Field");
        
        // GetText will retrieve all field codes and special characters
        System.out.println("GetText() Result: " + doc.getText());
        
        // ToString will export the node to the specified format. When converted to text it will not retrieve fields code
        // or special characters, but will still contain some natural formatting characters such as paragraph markers etc.
        // This is the same as "viewing" the document as if it was opened in a text editor.
        System.out.println("ToString() Result: " + doc.toString(SaveFormat.TEXT));

        Example:

        Exports the content of a node to string in HTML format using default options.
        Document doc = new Document(getMyDir() + "Document.doc");
        
        // Extract the last paragraph in the document to convert to HTML.
        Node node = doc.getLastSection().getBody().getLastParagraph();
        
        // When ToString is called using the SaveFormat overload then conversion is executed using default save options.
        // When saving to HTML using default options the following settings are set:
        //   ExportImagesAsBase64 = true
        //   CssStyleSheetType = CssStyleSheetType.Inline
        //   ExportFontResources = false
        String nodeAsHtml = node.toString(SaveFormat.HTML);
