Parameters
- contextNode
- Type: Aspose.Html.DomNode
The context is context node for the evaluation of this XPath expression.
If the IXPathEvaluator was obtained by casting the Document then this must be
owned by the same document and must be a Document, Element, Attr,
Text, CDATASection, Comment, ProcessingInstruction,
or XPathNamespace node. If the context node is a Text or a CDATASection,
then the context is interpreted as the whole logical text node as seen by XPath, unless the node is empty
in which case it may not serve as the XPath context. - type
- Type: Aspose.Html.Dom.XPathXPathResultType
If a specific type is specified, then the result will be coerced to return the
specified type relying on XPath conversions and fail if the desired coercion is not possible. This must
be one of the values of XPathResultType. - result
- Type: SystemObject
The result specifies a specific result object which may be reused and returned
by this method. If this is specified as null or the implementation does not reuse the specified
result, a new result object will be constructed and returned. For XPath 1.0 results, this object will be
of type IXPathResult.
Return Value
Type:
IXPathResultThe result of the evaluation of the XPath expression. For XPath 1.0 results, this object will be
of type
IXPathResult.
