XPathEvaluator: createNSResolver() method
This method adapts any DOM node to resolve namespaces so that an XPath expression can be easily evaluated relative to the context of the node where it appeared within the document.
This adapter works like the DOM Level 3 method Node.lookupNamespaceURI()
in resolving the namespace URI from a given prefix using
the current information available in the node's hierarchy at the time the method is
called, also correctly resolving the implicit xml prefix.
Syntax
js
createNSResolver(nodeResolver)
Parameters
nodeResolver-
A
Nodeto be used as a context for namespace resolution.
Return value
An XPathNSResolver object which resolves namespaces with respect to the
definitions in scope for a specified node.
