edit: now that the OP has removed the code snippet that he/she posted in the original question, my reply makes no sense anymore.

Looks overly complicated to find a tags where the href matches something

foreach my $a ($root->look_down (_tag => "a", href => qr{some url matc
+h})) {
    say "Found a tag with href to ", $a->attr ("href"), " and text ", 
+$a->as_text;
    }
