To do this reliably (assuming that's a real-life example up there), you are going to need to use some derivative of HTML::Parser--probably HTML::TokeParser, (which is recommended for small jobs),or HTML::TableExtract.

If you really are getting things out of table rows, then of course HTML::TableExtract is an easy call, and it's an easy module to use, and you're set. If a more general HTML solution is needed, then I would recommend something along the lines of the following pseudocode (using TokeParser): 

my ($temp,$flag);
while ($token = $parser->get_token) {
    if ($token eq $start_token) {
         $flag = 1
    } elsif ($token eq $end_token) {
         $flag = 0;
         return $temp if $temp =~/KEY/;
         $temp = '';
    }
    $temp .= $token if $flag;
}

Please note that this is NOT correct syntax for HTML::TokeParser (though it's not as far off as I was originally expecting it to be), it's just an approximation from which (hopefully) you can figure out how to do what you want to do.
