Namespace: Aspose.Html.Dom.Traversal.Filters
Assembly: Aspose.HTML.dll (25.2.0)
Filters are objects that know how to “filter out” nodes.

Fields
FILTER_ACCEPT
Accept the node. Navigation methods defined for NodeIterator or TreeWalker will return this node.
public const short FILTER_ACCEPT = 1
Field 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 = 2
Field 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 = 3
Field Value
SHOW_ALL
Show all Nodes.
public const long SHOW_ALL = 4294967295
Field 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 = 2
Field Value
SHOW_CDATA_SECTION
Show CDATASection nodes.
public const long SHOW_CDATA_SECTION = 8
Field Value
SHOW_COMMENT
Show Comment nodes.
public const long SHOW_COMMENT = 128
Field Value
SHOW_DOCUMENT
Show Document nodes.
public const long SHOW_DOCUMENT = 256
Field Value
SHOW_DOCUMENT_FRAGMENT
Show DocumentFragment nodes.
public const long SHOW_DOCUMENT_FRAGMENT = 1024
Field Value
SHOW_DOCUMENT_TYPE
Show DocumentType nodes.
public const long SHOW_DOCUMENT_TYPE = 512
Field Value
SHOW_ELEMENT
Show Element nodes.
public const long SHOW_ELEMENT = 1
Field 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 = 32
Field Value
SHOW_ENTITY_REFERENCE
Show EntityReference nodes.
public const long SHOW_ENTITY_REFERENCE = 16
Field 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 = 2048
Field Value
SHOW_PROCESSING_INSTRUCTION
Show ProcessingInstruction nodes.
public const long SHOW_PROCESSING_INSTRUCTION = 64
Field Value
SHOW_TEXT
Show Text nodes.
public const long SHOW_TEXT = 4
Field 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.
