Testing array of hash valuesby legLess (Hermit)
|on Dec 11, 2001 at 07:06 UTC ( #130850=perlquestion: print w/replies, xml )||Need Help??|
legLess has asked for the wisdom of the Perl Monks concerning the following question:
Two questions here:
I want to format and display a heading iff that heading's children contain data.
I expected the do_head sub to put an empty list into @data; said list would then evaluate as false in a scalar context. This doesn't work, of course, which is why I'm here. I'm sure this is based on my faulty understanding of arrays and hashes. I've re-read the Camel on this subject and not attained enlightenment. Help?
