Trying to parse XML file

[Kevin Old]

Hello everyone,

I'm new to parsing XML files.  I've got a somewhat working attempt,
but keep getting errors when certain elements are undefined.

Can't call method "as_text" on an undefined value at ./xmltreebuild.pl line 33.

Attached is the XML I'm trying to parse and xmltreebuild.pl.

Any suggestions on how to better do this are greatly appreciated.

Thanks,
Kevin
