tilly:

Thanks very much. This is an excellent solution because the code change is limited to a single line.

What used to be: 

    sub attachment_link_extractor
            {
                my ($tag, %attr) = @_;

                push(@links, values %attr)
                    if (($tag eq 'a') &&
                        ($attr{href} =~ m/attachments/));
            }

      my $p = HTML::LinkExtor->new(\&attachment_link_extractor);

... now becomes ... 
    $attachment_link_extractor =
        sub {
                my ($tag, %attr) = @_;

                push(@links, values %attr)
                    if (($tag eq 'a') &&
                        ($attr{href} =~ m/attachments/));
            };

      my $p = HTML::LinkExtor->new($attachment_link_extractor);

The only part of the your suggested change that confused me was the need to put a semicolon after the bracket that closes the subroutine. I don't remember ever writing Perl that way before, but, I keep forgetting that the subroutine itself is part of an assignment statement.
