Re: Regex failure interpretation

Syntax error. You ask for one char, you get one char. The + needs to be within the capture and then it works as advertised.

$_ =~ m[^([01]+)$] and print "$_:'$1'\n" for qw[ 0 1 00 11 10 01 012];
__DATA__
0:'0'
1:'1'
00:'00'
11:'11'
10:'10'
01:'01'

Not quite. As I mentioned above, I only want to capture the first character, not the whole string. Examine what is said, not who speaks. "Efficiency is intelligent laziness." -David Dunham "Think for yourself!" - Abigail	[reply] [d/l]
