Thanks Bob
Tried out your samples, and I think I'll probably roll with a Twig
solution.
It looks a heckuva lot more complicated than XML::Simple, but it
seems to actually work. Hopefully I can get past the learning curve ;-)
Are there any really good documentation references for XML::Twig you
might point me to?
Thanks.
