wisdom of the Perl Monks concerning the following question:
Hello and thank you again for your time.
I have been trying to figure this out for a few hours now. Arrays, hashes, array of hashes, hash of arrays, etc., they have always been confusing for me.
I am reading a small XML file with 6 values.
Only 'showAbbreviation' may or may not be empty. All others will always have a value. I've tried this...
I thought one of those would do the trick, but it is giving me back a 'HASH(0xd6a9690)' type value instead of an empty String value. I've tried exists and defined and not defined etc., but nothing is giving me the response I want.
What am I missing? This should be fairly easy I would think. Please help me understand, and thank you!
