Re: [xml] Newbie Help

Hi Bryan,

do you use namespaces in your xml file. If so, that one needs to be registered
first, before doing queries. In the future it is helpful to add a snipped of the
XML files as well, when asking.

Well that helps a bit, but the problem still remains that the list
shouldn't return empty.  Any thoughts?

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).
