You don't necessarily need the s-modifier here, only if you want to use the dot to match newline characters:

#!/usr/bin/perl

use strict;
use warnings;

my $string = << "STRING_END";
<TITLE>
RESULTADOS Y CLASIFICACIONES DE LA NBA
</TITLE>
STRING_END

print "matched without modifier\n" 
  if ($string =~ m{<TITLE>[^<]*RESULTADOS[^<]*</TITLE>});
print "matched with s modifier\n" 
  if ($string =~ m{<TITLE>.*?RESULTADOS.*?</TITLE>}s);

Note that both these solutions are imperfect, the first will not work for nested tags and the second will match if the keyword is anywhere between the first <TITLE> and the last </TITLE>, even if it's outside a title, e.g. <TITLE>something</TITLE>RESULTADOS<TITLE>else</TITLE> will match. Which is why regexes are usually a bad solution for this kind of problem, it would be better to parse the SGML and check the contents of TITLE nodes directly.


All dogma is stupid.
