Good to have it in the archives for future reference. Thanks for taking
the time to post it back.
I'd assume your production code is longer and more paranoid than the
fragment shown. XML::XPath requires error checking, even though it
doesn't return undef as so many do. E.g.,
> foreach my $kw ($item->find('KEYWORD')->get_nodelist){
Some documents might result in find() returning something that doesn't
respond to get_nodelist. In
http://search.cpan.org/~msergeant/XML-XPath-1.13/XPath.pm#nodeset_=_find
($path,_[$context])
says it could return
XML::XPath::NodeSet object containing the nodes it found
(or empty if no nodes matched the path), or one of
XML::XPath::Literal
(a string), XML::XPath::Number, or XML::XPath::Boolean. It should
always return something - and you can use ->isa() to find out what it
returned. If you need to check how many nodes it found you should
check
$nodeset->size
but even that isn't foolproof since XML::XPath::Boolean->size() is
apparently not supported either.
