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
XPathNSResolver XPathEvaluator.createNSResolver(nodeResolver);
Parameters
- nodeResolver
- A
Node
to 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.
