in reply to Regular Expression tricky newline problem

Use a non-greedy match:

#!/usr/bin/perl use strict; use warnings; local $/=undef; my $contents=<DATA>; my ($thirdline) = $contents =~ m/Line3 : (.*?)\n/s; print $thirdline."\n"; __DATA__ Line1 : Dit is de eerste regel Line2 : Dit is de tweede regel Line3 : Dit is de derde regel Line4 : Dit is de vierde regel
Output:
Dit is de derde regel
Or you could match against a negated character class:
my ($thirdline) = $contents =~ m/Line3 : ([^\n]+)/s;
