I create a twig using XML::Twig::XPath-new( ... ) and when I parse a file with my callback, I get this message when I call findnodes(): perl update_wishlist_archive.pl using findnodes() using findnodes() Can't locate object method "node_cmp" via package "XML::Twig::Elt" at ... XPath.pm line 17. It works the first couple of times and then it fails. Sorry this is so vague but I was wondering if anyone had seen this before and had a suggestion. Thanks, Ted
