That seems to have made a worse mess. Somehow ends up in a huge loop. :(

I read somewhere that <blah /> is correct syntax (same as <blah></blah>)
but that doesn't mean that XLM::Simple likes it any better.
Unfortunately, I can't change the input file much.
Relly all I am looking for is a way to test if a Hash has a legitimate
value in it, or is it going yo output that way.
Thanks for your help.
