Thanks for the response. FYI the other processor was Altova XMLSpy which from explanation is evaluation the xpath expression incorrectly.

I don't know what processor you're using that returns true, but Xalan-C is correct, and the XPath standard is explicit about this: http://www.w3.org/TR/xpath#node-tests "A QName in the node test is expanded into an expanded-name using the namespace declarations from the expression context. This is the same way expansion is done for element type names in start and end-tags except that the default namespace declared with xmlns is not used: if the QName does not have a prefix, then the namespace URI is null (this is the same way attribute names are expanded). It is an error if the QName has a prefix for which there is no namespace declaration in the expression context." Dave RE:
