What is the hosting language (such as C#, Java, PHP, ..., etc) in
which you are evaluating the XPath expressions?

You need to "register" the namespaces (the bindings (prefix,
namespace-uri)+) and then you can use any of the registered prefixes
in an XPath expression and its evaluation.

The rules for registering namespaces are different for different
hosting languages/environments.

Cheers,
Dimitre.
