Filters are objects that know how to “filter out” nodes.

protected NodeFilter()Fields
FILTER_ACCEPT
Accept the node. Navigation methods defined for NodeIterator or TreeWalker will return this node.
public const short FILTER_ACCEPT = 1Field Value
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.
public const short FILTER_REJECT = 2Field Value
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.
public const short FILTER_SKIP = 3Field Value
SHOW_ALL
Show all Nodes.
public const long SHOW_ALL = 4294967295Field Value
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.
public const long SHOW_ATTRIBUTE = 2Field Value
SHOW_CDATA_SECTION
Show CDATASection nodes.
public const long SHOW_CDATA_SECTION = 8Field Value
SHOW_COMMENT
Show Comment nodes.
public const long SHOW_COMMENT = 128Field Value
SHOW_DOCUMENT
Show Document nodes.
public const long SHOW_DOCUMENT = 256Field Value
SHOW_DOCUMENT_FRAGMENT
Show DocumentFragment nodes.
public const long SHOW_DOCUMENT_FRAGMENT = 1024Field Value
SHOW_DOCUMENT_TYPE
Show DocumentType nodes.
public const long SHOW_DOCUMENT_TYPE = 512Field Value
SHOW_ELEMENT
Show Element nodes.
public const long SHOW_ELEMENT = 1Field Value
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.
public const long SHOW_ENTITY = 32Field Value
SHOW_ENTITY_REFERENCE
Show EntityReference nodes.
public const long SHOW_ENTITY_REFERENCE = 16Field Value
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.
public const long SHOW_NOTATION = 2048Field Value
SHOW_PROCESSING_INSTRUCTION
Show ProcessingInstruction nodes.
public const long SHOW_PROCESSING_INSTRUCTION = 64Field Value
SHOW_TEXT
Show Text nodes.
public const long SHOW_TEXT = 4Field Value
Methods
AcceptNode(Node)
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.)
public abstract short AcceptNode(Node n)Parameters
n Node
node to check to see if it passes the filter or not.
Returns
a constant to determine whether the node is accepted, rejected, or skipped, as defined above.
GetPlatformType()
This method is used to retrieve ECMAScript object System.Type.
public override Type GetPlatformType()Returns
The ECMAScript object System.Type.
