I snipped the HTML you provided cause it was sooooo long. Try and trim it
down next time.
Anyhow, I think the code below does what you want.
use strict;
use warnings;
use HTML::Parser;
my $HTML = <<EOF;
<table border=0 cellpadding=0 cellspacing=0 width=156>
<tr>
<td colspan=2 bgcolor=#CDC9C0><b><font
face=verdana,arial,helvetica,sans-serif size=-2
color=#666666> Norske</font></b></td>
</tr>
<tr>
<td width=78 valign=top><font class=link-00-ul-l size=1>
<input type="checkbox" name=kanal_id[] value=1 CHECKED>
<a href="index.html?kanal_id=1&dag=0&fra_tid=0&til_tid=24&kategori_id=">NRK
1</a><br>
<input type="checkbox" name=kanal_id[] value=3 >
<a href="index.html?kanal_id=3&dag=0&fra_tid=0&til_tid=24&kategori_id=">TV
2</a><br>
<input type="checkbox" name=kanal_id[] value=5 >
<a
href="index.html?kanal_id=5&dag=0&fra_tid=0&til_tid=24&kategori_id=">TVNorge
</a><br>
</font></td>
</tr>
</table>
EOF
my $current_tag; # i'm not happy with using this.
# is there a better way? anyone?
my $p = HTML::Parser->new(
api_version => 3,
start_h => [ \&start_tag, 'tagname,attr' ],
text_h => [ \&text, 'text' ]
);
$p->parse($HTML);
$p->eof;
sub start_tag
{
my $name = shift;
my $attrs = shift;
my $text = shift;
$current_tag = $name;
if ($name eq 'input' and $attrs->{'type'} eq 'checkbox')
{
print $attrs->{'value'}, "=";
}
}
sub text
{
my $text = shift;
if ($current_tag eq 'a')
{
print "$text\n";
}
}
