I'm trying to create a robust way of detecting which season and episode a TV show is from.

Common patterns are things like "S5E6", "S5.E6", or "S05xE06" but there's no real consistency.

Also I want to fall back to detecting a date for shows like The Daily Show, which don't really have seasons/episodes.

So here's my first attempt, please comment. Also if you're interested, please test on bulk data from TV torrent websites, which is what I'm doing right now.

One straightforward question: what's the best-practice way to remove leading zeros? Convert to a number with something like $foo = ($foo + 0)? Strip the zeros as characters? sprintf? 

#!/usr/local/bin/perl
use strict;
use warnings;
use Data::Dumper::Simple;
use Regexp::Common qw(time);

my ( $count, $success, $failure ) = ( 0, 0, 0 );
while (<DATA>) {
    chomp;
    $count++;
    my $data = extract_show_info($_);
    if ($data) {
        print "Success? \n";
        print Dumper($data);
        $success++;
    } else {
        print "Failure: $_\n";
        $failure++;
    }

}

print "Processed: $count | Successes: $success | Failures: $failure \n
+";

sub extract_show_info {
    my $input_string = shift();
    my $result       = undef;

    if ( $result = extract_episode_data($input_string) ) {
        $result->{type} = 'se';
    } elsif ( my @date = $_ =~ /$RE{time}{ymd}{-keep}/ ) {
        $result = {
            type  => 'date',
            year  => $date[1],
            month => $date[2],
            day   => $date[3]
        };
    }
    return $result;

}

sub extract_episode_data {
    my $input_string = shift();
    if (   $input_string =~ /s(\d+)\s*e(\d+)/i
        || $input_string =~ /s(\d+)\.e(\d+)/i
        || $input_string =~ /(\d+)x(\d+)/i
        || $input_string =~ /Season\s*(\d+),?\s*Episode\s*(\d+)/i
        || $input_string =~ /Series\.(\d+)\.(\d+)/ )
    {
        my $episode_data = { season => $1, episode => $2 };
        return $episode_data;
    } else {
        return;
    }

}
