Your question has inspired me this code, based on Joel Berger post
<http://blogs.perl.org/users/joel_berger/2012/05/using-mojodom.html>, that
finds *a href *tags in a page (I am also a beginner ;-) ).
#!/usr/bin/env perl
use Modern::Perl;
use Mojo::UserAgent;
use Mojo::DOM;
my $ua = Mojo::UserAgent->new;
my $page = $ua->get('http://mojolicious.org/')->res->dom;
my $dom = Mojo::DOM->new($page);
foreach my $a_href ( $dom->find('a[href]')->each ) {
say $a_href;
}
I am sorry it does not answer your question, but I hope it helps.
Cheers!
