Re: Storing Lines before and After pattern

Because of $` and $' overhead, this is an ideal place for split:

open ($fh, "<poem") or die "Couldn't Open!";
$poem = do{ local $/; <$fh> };
($before, $match, $after} = split /(DOG)/, $poem;

If there may be multiple occurrences of DOG, you want: `($before, $match, $after) = split /(DOG)/, $poem, 2;` [download] or $after will only include up to the second DOG.	[reply] [d/l]
