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 前缀。

句法

XPathNSResolver XPathEvaluator.createNSResolver(nodeResolver);
					

参数

nodeResolver

节点 to be used as a context for namespace resolution.

返回值

XPathNSResolver object which resolves namespaces with respect to the definitions in scope for a specified node.
