Inspired by some of the appalling TV listings websites, I decided I'd roll my own page with this script. It takes an XMLTV format input file (which can contain multiple channels) and generates a webpage with the times approximately aligned and the descriptions on mouseover. I have a seperate script which downloads the xml data from http://www.bleb.org/tv/data/listings/ you can see an example of the output at http://patter.mine.nu/~steve/newTV/ but please be gentle, I don't have much bandwidth.

use XML::Simple;

my $tv = XMLin('raw.xml');

# channel names & global channel info - array of hashes
# can xref with programs by key: blebid
my $chan_names = $tv->{xmltvid};
# generate cross-referencing hash
my $chan_names = $tv->{xmltvid};
# generate cross-referencing hash
my %xmltvid;
foreach my $chan (@$chan_names) {
    $xmltvid{$chan->{content}} = $chan->{blebid};
}

# programs on BBC 1 - ref to array of hashes [example]
# my $channel = $tv->{channel}->{$xmltvid{'BBC 1'}}->{programme};
# &all_shows($channel, 'BBC 1');

print "<table border>\n";
&all_shows();
print "</table>\n";
sub all_shows {
    # my ($chanref, $channame) = @_;
    print "<tr>\n";
    foreach my $chan (keys %xmltvid) {
        print "  <th>$chan</th>\n";
    }
    foreach my $hour (0 .. 23) {

        &this_hour($tv, $hour);
        print "</tr>\n<tr>\n";
        &this_hour($tv, $hour);

    }
}

sub this_hour {
    my ($tvref, $hour) = @_;
    # print '<pre>', Dumper $tvref, '</pre>';
    foreach my $chan (keys %xmltvid) {
        # my $chan = 'BBC 1';
        my $chanref =  $tvref->{channel}->{$xmltvid{$chan}}->{programm

        print "  <td>";

        my $i = 0;
        foreach my $prog (@$chanref) {
            if (substr($prog->{start}, 0, 2) == $hour) {
                print '<table><tr><td>', $prog->{start}, '-',
                $prog->{end}, '</td>',
                "<td><div title='$prog->{subtitle} $prog->{desc}'>$pro
+g->{title}",
                "</div></td></tr></table>";
            }
        }
    }
}

The other script which fetches the XMLTV data is a crufty little shell script which could probably be perlified with LWP::Simple and Archive::Zip, but its simpler this way :)
