java.lang.Objectorg.jaxen.dom.NamespaceNode
public class NamespaceNode
Extension DOM2/DOM3 node type for a namespace node.
This class implements the DOM2 and DOM3 Node interface
to allow namespace nodes to be included in the result
set of an XPath selectNodes operation, even though DOM does
not model namespaces in scope as separate nodes.
While all of the DOM2 methods are implemented with reasonable defaults, there will be some unexpected surprises, so users are advised to test for NamespaceNodes and filter them out from the result sets as early as possible.
getNodeType() method returns NAMESPACE_NODE,
which is not one of the usual DOM2 node types. Generic code may
fall unexpectedly out of switch statements, for example.getOwnerDocument() method returns the owner document
of the parent node, but that owner document will know nothing about
the namespace node.
isSupported(java.lang.String, java.lang.String) method always returns false.All attempts to modify a NamespaceNode will fail with a DOMException (DOMException.NO_MODIFICATION_ALLOWED_ERR).
