Constructor Detail

• Section

  public Section(DocumentBase doc)

  Initializes a new instance of the Section class.

  When the section is created, it belongs to the specified document, but is not yet part of the document and ParentNode is null.

  To include Section into a document use Document.InsertAfter, Document.InsertBefore or Sections.Add and Section.Insert methods.

  Parameters:

  doc - The owner document.

  Example:

  Shows how to construct an Aspose.Words document by hand.

  Document doc = new Document();
  
  // A blank document contains one section, one body and one paragraph.
  // Call the "RemoveAllChildren" method to remove all those nodes,
  // and end up with a document node with no children.
  doc.removeAllChildren();
  
  // This document now has no composite child nodes that we can add content to.
  // If we wish to edit it, we will need to repopulate its node collection.
  // First, create a new section, and then append it as a child to the root document node.
  Section section = new Section(doc);
  doc.appendChild(section);
  
  // Set some page setup properties for the section.
  section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
  section.getPageSetup().setPaperSize(PaperSize.LETTER);
  
  // A section needs a body, which will contain and display all its contents
  // on the page between the section's header and footer.
  Body body = new Body(doc);
  section.appendChild(body);
  
  // Create a paragraph, set some formatting properties, and then append it as a child to the body.
  Paragraph para = new Paragraph(doc);
  
  para.getParagraphFormat().setStyleName("Heading 1");
  para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);
  
  body.appendChild(para);
  
  // Finally, add some content to do the document. Create a run,
  // set its appearance and contents, and then append it as a child to the paragraph.
  Run run = new Run(doc);
  run.setText("Hello World!");
  run.getFont().setColor(Color.RED);
  para.appendChild(run);
  
  Assert.assertEquals("Hello World!", doc.getText().trim());
  
  doc.save(getArtifactsDir() + "Section.CreateManually.docx");

Property Getters/Setters Detail

• getBody

  public Body getBody()
  

  Returns the Body child node of the section.

  Body contains main text of the section.

  Returns null if the section does not have a Body node among its children.

  Example:

  Clears main text from all sections from the document leaving the sections themselves.

  Document doc = new Document();
  
  // A blank document contains one section, one body and one paragraph.
  // Call the "RemoveAllChildren" method to remove all those nodes,
  // and end up with a document node with no children.
  doc.removeAllChildren();
  
  // This document now has no composite child nodes that we can add content to.
  // If we wish to edit it, we will need to repopulate its node collection.
  // First, create a new section, and then append it as a child to the root document node.
  Section section = new Section(doc);
  doc.appendChild(section);
  
  // A section needs a body, which will contain and display all its contents
  // on the page between the section's header and footer.
  Body body = new Body(doc);
  section.appendChild(body);
  
  // This body has no children, so we cannot add runs to it yet.
  Assert.assertEquals(0, doc.getFirstSection().getBody().getChildNodes(NodeType.ANY, true).getCount());
  
  // Call the "EnsureMinimum" to make sure that this body contains at least one empty paragraph. 
  body.ensureMinimum();
  
  // Now, we can add runs to the body, and get the document to display them.
  body.getFirstParagraph().appendChild(new Run(doc, "Hello world!"));
  
  Assert.assertEquals("Hello world!", doc.getText().trim());

• 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 traverse through a composite node's collection of child nodes.

  Document doc = new Document();
  
  // Add two runs and one shape as child nodes to the first paragraph of this document.
  Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
  paragraph.appendChild(new Run(doc, "Hello world! "));
  
  Shape shape = new Shape(doc, ShapeType.RECTANGLE);
  shape.setWidth(200.0);
  shape.setHeight(200.0);
  // Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
  shape.setCustomNodeId(100);
  shape.setWrapType(WrapType.INLINE);
  paragraph.appendChild(shape);
  
  paragraph.appendChild(new Run(doc, "Hello again!"));
  
  // Iterate through the paragraph's collection of immediate children,
  // and print any runs or shapes that we find within.
  NodeCollection children = paragraph.getChildNodes();
  
  Assert.assertEquals(3, paragraph.getChildNodes().getCount());
  
  for (Node child : (Iterable<Node>) children)
      switch (child.getNodeType()) {
          case NodeType.RUN:
              System.out.println("Run contents:");
              System.out.println("\t\"{child.GetText().Trim()}\"");
              break;
          case NodeType.SHAPE:
              Shape childShape = (Shape) child;
              System.out.println("Shape:");
              System.out.println("\t{childShape.ShapeType}, {childShape.Width}x{childShape.Height}");
              break;
      }

• getCount

  public int getCount()
  

  Gets the number of immediate children of this node.

  Example:

  Shows how to add, update and delete child nodes in a CompositeNode's collection of children.

  Document doc = new Document();
  
  // An empty document, by default, has one paragraph.
  Assert.assertEquals(1, doc.getFirstSection().getBody().getParagraphs().getCount());
  
  // Composite nodes such as our paragraph can contain other composite and inline nodes as children.
  Paragraph paragraph = doc.getFirstSection().getBody().getFirstParagraph();
  Run paragraphText = new Run(doc, "Initial text. ");
  paragraph.appendChild(paragraphText);
  
  // Create three more run nodes.
  Run run1 = new Run(doc, "Run 1. ");
  Run run2 = new Run(doc, "Run 2. ");
  Run run3 = new Run(doc, "Run 3. ");
  
  // The document body will not display these runs until we insert them into a composite node
  // that itself is a part of the document's node tree, as we did with the first run.
  // We can determine where the text contents of nodes that we insert
  // appears in the document by specifying an insertion location relative to another node in the paragraph.
  Assert.assertEquals("Initial text.", paragraph.getText().trim());
  
  // Insert the second run into the paragraph in front of the initial run.
  paragraph.insertBefore(run2, paragraphText);
  
  Assert.assertEquals("Run 2. Initial text.", paragraph.getText().trim());
  
  // Insert the third run after the initial run.
  paragraph.insertAfter(run3, paragraphText);
  
  Assert.assertEquals("Run 2. Initial text. Run 3.", paragraph.getText().trim());
  
  // Insert the first run to the start of the paragraph's child nodes collection.
  paragraph.prependChild(run1);
  
  Assert.assertEquals("Run 1. Run 2. Initial text. Run 3.", paragraph.getText().trim());
  Assert.assertEquals(4, paragraph.getChildNodes(NodeType.ANY, true).getCount());
  
  // We can modify the contents of the run by editing and deleting existing child nodes.
  ((Run) paragraph.getChildNodes(NodeType.RUN, true).get(1)).setText("Updated run 2. ");
  paragraph.getChildNodes(NodeType.RUN, true).remove(paragraphText);
  
  Assert.assertEquals("Run 1. Updated run 2. Run 3.", paragraph.getText().trim());
  Assert.assertEquals(3, paragraph.getChildNodes(NodeType.ANY, true).getCount());

• getCustomNodeId/setCustomNodeId

  public int getCustomNodeId() / public void setCustomNodeId(int value)
  

  Specifies custom node identifier.

  Default is zero.

  This identifier can be set and used arbitrarily. For example, as a key to get external data.

  Important note, specified value is not saved to an output file and exists only during the node lifetime.

  Example:

  Shows how to traverse through a composite node's collection of child nodes.

  Document doc = new Document();
  
  // Add two runs and one shape as child nodes to the first paragraph of this document.
  Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
  paragraph.appendChild(new Run(doc, "Hello world! "));
  
  Shape shape = new Shape(doc, ShapeType.RECTANGLE);
  shape.setWidth(200.0);
  shape.setHeight(200.0);
  // Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
  shape.setCustomNodeId(100);
  shape.setWrapType(WrapType.INLINE);
  paragraph.appendChild(shape);
  
  paragraph.appendChild(new Run(doc, "Hello again!"));
  
  // Iterate through the paragraph's collection of immediate children,
  // and print any runs or shapes that we find within.
  NodeCollection children = paragraph.getChildNodes();
  
  Assert.assertEquals(3, paragraph.getChildNodes().getCount());
  
  for (Node child : (Iterable<Node>) children)
      switch (child.getNodeType()) {
          case NodeType.RUN:
              System.out.println("Run contents:");
              System.out.println("\t\"{child.GetText().Trim()}\"");
              break;
          case NodeType.SHAPE:
              Shape childShape = (Shape) child;
              System.out.println("Shape:");
              System.out.println("\t{childShape.ShapeType}, {childShape.Width}x{childShape.Height}");
              break;
      }

• 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 how to create a node and set its owning document.

  Document doc = new Document();
  Paragraph para = new Paragraph(doc);
  para.appendChild(new Run(doc, "Hello world!"));
  
  // We have not yet appended this paragraph as a child to any composite node.
  Assert.assertNull(para.getParentNode());
  
  // If a node is an appropriate child node type of another composite node,
  // we can attach it as a child only if both nodes have the same owner document.
  // The owner document is the document we passed to the node's constructor.
  // We have not attached this paragraph to the document, so the document does not contain its text.
  Assert.assertEquals(para.getDocument(), doc);
  Assert.assertEquals("", doc.getText().trim());
  
  // Since the document owns this paragraph, we can apply one of its styles to the paragraph's contents.
  para.getParagraphFormat().setStyleName("Heading 1");
  
  // Add this node to the document, and then verify its contents.
  doc.getFirstSection().getBody().appendChild(para);
  
  Assert.assertEquals(doc.getFirstSection().getBody(), para.getParentNode());
  Assert.assertEquals("Hello world!", doc.getText().trim());

• getFirstChild

  public Node getFirstChild()

      // Invoke the recursive function that will go through and print all the child nodes of a composite node.
      traverseAllNodes(doc, 0);
  }
  
  /// <summary>

Method Detail

• accept

  public 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.

  Calls DocumentVisitor.VisitSectionStart, then calls Accept for all child nodes of the section and calls DocumentVisitor.VisitSectionEnd at the end.

  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.

• 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 DocumentBase.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:

  Shows how to construct an Aspose.Words document by hand.

  Document doc = new Document();
  
  // A blank document contains one section, one body and one paragraph.
  // Call the "RemoveAllChildren" method to remove all those nodes,
  // and end up with a document node with no children.
  doc.removeAllChildren();
  
  // This document now has no composite child nodes that we can add content to.
  // If we wish to edit it, we will need to repopulate its node collection.
  // First, create a new section, and then append it as a child to the root document node.
  Section section = new Section(doc);
  doc.appendChild(section);
  
  // Set some page setup properties for the section.
  section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
  section.getPageSetup().setPaperSize(PaperSize.LETTER);
  
  // A section needs a body, which will contain and display all its contents
  // on the page between the section's header and footer.
  Body body = new Body(doc);
  section.appendChild(body);
  
  // Create a paragraph, set some formatting properties, and then append it as a child to the body.
  Paragraph para = new Paragraph(doc);
  
  para.getParagraphFormat().setStyleName("Heading 1");
  para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);
  
  body.appendChild(para);
  
  // Finally, add some content to do the document. Create a run,
  // set its appearance and contents, and then append it as a child to the paragraph.
  Run run = new Run(doc);
  run.setText("Hello World!");
  run.getFont().setColor(Color.RED);
  para.appendChild(run);
  
  Assert.assertEquals("Hello World!", doc.getText().trim());
  
  doc.save(getArtifactsDir() + "Section.CreateManually.docx");

• appendContent

  public void appendContent(Section sourceSection)

  Inserts a copy of content of the source section at the end of this section.

• 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:

• 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:

  // Composite nodes such as our paragraph can contain other composite and inline nodes as children.
  Paragraph paragraph = doc.getFirstSection().getBody().getFirstParagraph();
  Run paragraphText = new Run(doc, "Initial text. ");
  paragraph.appendChild(paragraphText);
  
  // Create three more run nodes.
  Run run1 = new Run(doc, "Run 1. ");
  Run run2 = new Run(doc, "Run 2. ");
  Run run3 = new Run(doc, "Run 3. ");
  
  // The document body will not display these runs until we insert them into a composite node
  // that itself is a part of the document's node tree, as we did with the first run.

  while (e.hasNext()) {
      Node currentNode = e.next();
      System.out.println(MessageFormat.format("Table paragraph index {0}, contents: \"{1}\"", index++, currentNode.getText().trim()));
  }
  
  // This expression will select any paragraphs that are direct children of any Body node in the document.
  nodeList = doc.selectNodes("//Body/Paragraph");
  
  // We can treat the list as an array.
  Assert.assertEquals(nodeList.toArray().length, 4);
  
  // Use SelectSingleNode to select the first result of the same expression as above.

  // The NodeList that results from this XPath expression will contain all nodes we find inside a field.
  // However, FieldStart and FieldEnd nodes can be on 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.
  System.out.println("Contents of the first Run node that's part of a field: {resultList.First(n => n.NodeType == NodeType.Run).GetText().Trim()}");

• selectSingleNode

      // 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("List item paragraph #{0}", listParaCount));
  
          // This is the text we get when getting when we output this node to text format.
          // This text output will omit list labels. 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 the current level of the list. If we have a list with multiple levels,
          // this will tell us what position it is on that level.
          System.out.println("\tNumerical Id: {label.LabelValue}");
  
          // Combine them together to include the list label with the text in the output.
          System.out.println("\tList label combined with text: {label.LabelString} {paragraphText}");
      }

  Example:

  Exports the content of a node to String in HTML format.

  Document doc = new Document(getMyDir() + "Document.docx");
  
  Node node = doc.getLastSection().getBody().getLastParagraph();
  
  // When we call the ToString method using the html SaveFormat overload,
  // it converts the node's contents to their raw html representation.
  Assert.assertEquals("<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%; font-size:12pt\">" +
          "<span style=\"font-family:'Times New Roman'\">Hello World!</span>" +
          "</p>", node.toString(SaveFormat.HTML));
  
  // We can also modify the result of this conversion using a SaveOptions object.
  HtmlSaveOptions saveOptions = new HtmlSaveOptions();

  Example:

  Shows the difference between calling the GetText and ToString methods on a node.

  Document doc = new Document();
  
  DocumentBuilder builder = new DocumentBuilder(doc);
  builder.insertField("MERGEFIELD Field");
  
  // GetText will retrieve the visible text as well as field codes and special characters.
  Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());
  
  // ToString will give us the document's appearance if saved to a passed save format.
  Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));
