in reply to Regex only the longes Value , and possible speedup Problem

You could use this:
#!/usr/bin/perl use strict; use warnings; my @numbers = ('012345','0123456'); @numbers = sort{length $b <=> length $a}@numbers; my $regex = join('|',@numbers); my $string = '0123456778945'; $string =~ s!^($regex)(.*)!$1;$2!; print $string;
