You didn't include the call to XML::Simple, but I have a feeling the
problem is that you need to use ForceArray in XML::Simple, and then
traverse the expected arrays.  Without ForceArray, you'll sometimes get
an array of hashes and sometimes just a hash (if there's only one).
The man page for XML::Simple will explain it all.

Also, reposting the same message to the same list is not going to be
effective.  It's likely to cause other posters to actively ignore
you when they may otherwise have tried to help.  If you have more
information, it's best to reply to the original thread and include only
the new information.
