Thanks for the info, I got it working with the default namespace. One
more thing, neither xmlXPathEval nor xmlXPathCompiledEval return NULL
when they don't find the desired expression. Am I correct to assume this
is because even an empty node set is a valid object?


  yes,

Do I need to check
the node set value's nodeNr to determine if it is empty or is there a
better mechanism.


  yes ... and don't forget to free the object too.
