Declaring the function looks okay to me, though I'm not so sure about
the internals of the function.
Have you tried a version of getDataDetailValue() that just does the same
as xsltExtFunctionTest (though maybe with popping more function
arguments)?

If you want the string value, you can use xmlXPathPopString() [1]

Previously you used the return value of this function.

Don't you need to free one or more of the versions of msg?
