Who knows? We don't have the data you are trying to process. My guess is that the xpath pattern being searched for is not found in the document you are trying to process. --MidLifeXis	[reply]

Who said anything about it being unassigned?!? It's undefined which means the findnodes() on line 11 returned an undef. The notoriously bad docs of XML::LibXML do not say anything about what's this method supposed to return if the XPath query doesn't match anything, but an undef is a quite way to return "nothing". Even though rereading the docs it seems it's supposed to return a XML::LibXML::NodeList object in scalar context no matter what. Jenda Enoch was right! Enjoy the last years of Rome.	[reply]
