Supplying the leading / is one of the permutations of the expression

xmlXPathNodeCollectAndTest xpath.c:1923 : nodelist and node are NULL
However, xpath_object is still returned as NULL. According to the
documentation, even if there are no matches, shouldn't I receive back a
valid pointer to an empty list?
No, you may get NULL for an empty Nodeset. It's an optimization
which made huge difference for XSLT performances (no need to allocate/
deallocate empty lists all the time).
