Your XPath probably includes the name of the element against which you
were trying to execute the XPath. That works OK if you're starting at a
document node (because that elt is its first child), but not if you're
at the element itself.
Say you have:
If you start your XPath at the document, then "a/b" returns "b". If you
start at "a", you'll get nothing because "a" has no child named "a"
which is what "a/b" would be asking for.
