What am I doing wrong?
You are not showing us a complete program that generates some other
output than the output you were expecting.
A couple of observations besides that:
- Not all numbers at those lines include digits before and after a
decimal point.
- The '.' character has a special meaning when used in a regex outside a
character class, and should therefore be escaped.
This code:
(-?\d+(?:\.\d+)?)
would match any of those numbers.
Better yet, use Regexp::Common:
use Regexp::Common qw(number);
/(\w+)(?:\s+$RE{num}{real}){3,3}\s+(\w+)/;
