You need to provide a complete, _minimal_ code sample along with a sample 
input document and XPath expression for anyone to help you.

If you are constucting a Xerces DOM instance programmatically, you must 
make sure you are creating a namespace-aware DOM.  If you are parsing to a 
Xerces DOM instance, you need to make sure the parser you're using is 
properly configured for namespace processing.
