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

Your usage of grep is incorrect. In your first script, use

if ( !grep(/$key/, @keysToKeep) )

to make it work.

> `if ( !grep(/$key/, @keysToKeep) )` Careful! Without anchors you'll also match on substrings, so better `/^$key$/`. Anyway try to avoid regexes when possible and use `eq` `if ( not grep { $key eq $_ } @keysToKeep) )` Cheers Rolf ( addicted to the Perl Programming Language) edit corrected code	[reply] [d/l] [select]

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]
