Re^2: Parsing an Array of Hashes, Modifying Key/Value Pairs

Careful! Without anchors you'll also match on substrings, so better /^$key$/.

Anyway try to avoid regexes when possible and use eq

if ( not grep { $key eq $_ } @keysToKeep) )

Good catch! When I'm playing with regex, I use GSkinners test suite (as I'm without a doubt, no wizard) The regex fail in the OP was very much glassed over by me as I knew it wasn't doing anything that was getting me towards my end goal. http://gskinner.com/RegExr/ -- Libra	[reply]
