NodeFilter Class

Filters are objects that know how to "filter out" nodes.

Inheritance Hierarchy

Namespace: Aspose.Html.Dom.Traversal.Filters
Assembly: Aspose.HTML (in Aspose.HTML.dll) Version: 21.1

Syntax

C++

public abstract class NodeFilter : DOMObject, 
	INodeFilter

Public MustInherit Class NodeFilter
	Inherits DOMObject
	Implements INodeFilter

public ref class NodeFilter abstract : public DOMObject, 
	INodeFilter

[<AbstractClassAttribute>]
type NodeFilter =  
    class
        inherit DOMObject
        interface INodeFilter
    end

The NodeFilter type exposes the following members.

Constructors

	Name	Description
	NodeFilter	Initializes a new instance of the NodeFilter class

Methods

	Name	Description
	AcceptNode	Test whether a specified node is visible in the logical view of a TreeWalker or NodeIterator. This function will be called by the implementation of TreeWalker and NodeIterator; it is not normally called directly from user code. (Though you could do so if you wanted to use the same filter to guide your own application logic.)
	Equals	(Inherited from Object.)
	Finalize	(Inherited from Object.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	ToString	(Inherited from Object.)

Fields

	Name	Description
	FILTER_ACCEPT	Accept the node. Navigation methods defined for NodeIterator or TreeWalker will return this node.
	FILTER_REJECT	Reject the node. Navigation methods defined for NodeIterator or TreeWalker will not return this node. For TreeWalker, the children of this node will also be rejected. NodeIterators treat this as a synonym for FILTER_SKIP.
	FILTER_SKIP	Skip this single node. Navigation methods defined for NodeIterator or TreeWalker will not return this node. For both NodeIterator and TreeWalker, the children of this node will still be considered.
	SHOW_ALL	Show all Nodes.
	SHOW_ATTRIBUTE	Show Attr nodes. This is meaningful only when creating an iterator or tree-walker with an attribute node as its root; in this case, it means that the attribute node will appear in the first position of the iteration or traversal. Since attributes are never children of other nodes, they do not appear when traversing over the document tree.
	SHOW_CDATA_SECTION	Show CDATASection nodes.
	SHOW_COMMENT	Show Comment nodes.
	SHOW_DOCUMENT	Show Document nodes.
	SHOW_DOCUMENT_FRAGMENT	Show DocumentFragment nodes.
	SHOW_DOCUMENT_TYPE	Show DocumentType nodes.
	SHOW_ELEMENT	Show Element nodes.
	SHOW_ENTITY	Show Entity nodes. This is meaningful only when creating an iterator or tree-walker with an Entity node as its root; in this case, it means that the Entity node will appear in the first position of the traversal. Since entities are not part of the document tree, they do not appear when traversing over the document tree.
	SHOW_ENTITY_REFERENCE	Show EntityReference nodes.
	SHOW_NOTATION	Show Notation nodes. This is meaningful only when creating an iterator or tree-walker with a Notation node as its root; in this case, it means that the Notation node will appear in the first position of the traversal. Since notations are not part of the document tree, they do not appear when traversing over the document tree.
	SHOW_PROCESSING_INSTRUCTION	Show ProcessingInstruction nodes.
	SHOW_TEXT	Show Text nodes.
