Matt, Do you have any code that would implement support of Namespaces on elements?

What is the > deal with Elements? Thanks. Hi, Joe. It's more a case of "what is the deal with attributes?" It just so happens that a DOM or JDOM element node knows how to set its attributes. Not so for elements. In this case you must implement and set an AbstractFactory on your JXPathContext.
