Thanks for replying. I did read those threads (in fact I started one of them) but still being relatively new to perl I am having trouble. I notice the following: My code will retrieve XML results from a web page. The value below will always have data: $xml->{result}->{covers} Mostly it will be just a folder path. However, sometimes it could be more than one path in which case the following is returned:
So when the XML appears I should look for $result->{covers}->{1}->{content} but this is where the error appears. I'm gonna read up some more and maybe I'll figure it out. Thanks for the replies though.
