context
is context node for theevaluation of this XPath expression. If the XPathEvaluator was obtained by casting the Document
then this must be owned by the same document and must be a Document
, Element
, Attribute
, 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.
@param resolver The resolver
permits translation ofprefixes within the XPath expression into appropriate namespace URIs . If this is specified as null
, any namespace prefix within the expression will result in DOMException
being thrown with the code NAMESPACE_ERR
.
@param type If a specific type
is specified, then theresult will be returned as the corresponding type.For XPath 1.0 results, this must be one of the codes of the XPathResult
interface.
@param result The result
specifies a specific resultobject 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 XPathResult
.
@return The result of the evaluation of the XPath expression.For XPath1.0 results, this object will be of type XPathResult
.
