XSL value-of select isn't working

Question

I can't figure out why my code is not working, the only way i can get any xsl to to render is if i use the . operator when using value-of select which just prints out every value of my xml. If you change the value-of select="hey" to just "." it will show everything but when i try to just select a specific element I get nothing.

This is the code I am working with :

Answer 1

It's the #1 problem reported here with XSLT (about one question a day): your XML is in a namespace, but your path expressions / match patterns are looking for elements in no namespace.
