You may also wish to use the m/regex/si flags in case the HTML spans multiple lines or the VERIFIER name attribute is not upper-cased. No good deed goes unpunished. -- (attributed to) Oscar Wilde	[reply]

Who says 'Fun with regexes' is not a contact sport? `$text .= 'blah<input type="hidden" name="FOO" value="123-01">blah'; $text .= "\nblah\n"; $text .= 'blah<input type="hidden" name="VERIFIER" value="076-62">blah +'; $text .= "\nblah\n"; $page = (($text =~ m/name="VERIFIER"\ value="([-0-9]+?)">/xg),$1)[0]; print "$page";` [download] So, $page will end up as "076-62" in your example... and to hell with $1. If you wanted make it more interesting, you could replace the appropriate line with: `$page = (($text =~ m/<input\ type="hidden"\ name="VERIFIER"\ value="(\ +d+)\-(\d+)">/xg),$1.'-'.$2)[0];` [download] or `$page = (($text =~ m/<input\ type="hidden"\ name="VERIFIER"\ value="(\ +d+)\-(\d+)">/xg),$1.'-'.$2)[1];` [download] if you only wanted a portion of the value. (The '072' or '062' in your example.) FYI, the 'special character' that's goofing with you (at least as written in your example) is the space between `"VERIFIER"` and `value`. The `"` characters do not have to be backwhack-escaped, but that non-escaped space in the middle of your regex will cause the match to fail. Well, that's my $.02 worth.
