Hi luxs,

Since I'm guessing the <img> tags can be nested arbitrarily deep, the CSS selector "img, h1" was going to be my next suggestion.

There are many other ways to write the logic, here's one:

use warnings;
use strict;
use Mojo::DOM;

my $data = <<'ENDDATA';
yada...yada...yada..
<img src="111">
yada...yada...yada..
<img src="222">
yada...yada...yada..
<h1>Some title</h1>
yada...yada...yada..
<a href="444444">
<img src="333">
yada...yada...yada..
<img src="444">
ENDDATA

my $dom = Mojo::DOM->new($data);
my (@imgs,$seen_h1);
for my $tag ( $dom->find('h1, img')->each ) {
    if ($seen_h1 && $tag->tag eq 'img' && length $tag->attr('src'))
        { push @imgs, $tag }
    elsif ($tag->tag eq 'h1')
        { $seen_h1 = 'true' }
}
print $_->attr('src'),"\n" for @imgs;

__END__

You don't even need the intermediate @imgs array and can print directly from the first loop if you like.

Hope this helps,
