[jdom-interest] XPath Namespace mappings

[Phil Weighill-Smith]

Clearly, this is only applicable when you have a document you can apply the path to but you could:
 
Apply the XPath to a document to obtain a (set of) JDOM "node"(s), then walk up the JDOM hierarchy(ies) getting the namespaces for each of the nodes in the path(s).

	Neither JDOM's nor Jaxen's XPath objects have methods to retrieve the
	configured namespaces.
	
	When dealing with namespaces, I usually code a method to allocate XPath
	objects that also takes care of adding all the namespaces used by the
	application to every created XPath instance.
