Because I don't know how to do it efficiently if possible, ie without 10 lines like :

First do it any way possible, later reduce it :)

Anyway ,

for my $ret ( $dom->find('div.ret')->each ){
    for my $aaaa ( $ret->find('a')->each ){
        my $date = $aaaa->find('div.date')->first->all_text;
        my $lieu = $aaaa->find('div.lieu')->first->all_text;
        my $cat  = $aaaa->find('div.cat')->first->all_text;
        my $titl = $aaaa->find('h2.title')->first->all_text;
        print join( "\t#\t", $date, $lieu, $cat, $titl), "\n";
    }
}
__END__

Thank you very much, work is done ^^

According to my understanding (perhaps wrong), find is not optimal (with a lot of html files) instead of selecting fields from parent with child nodes but I dont know how to manipulate children / child_notes and so on..

Something like that :

for each loop = child of ret
do
  url1 = loop.child[1].href
  date = loop.child[2].child[1].child[1].text +   loop.child[2].child[
+1].child[2].text + loop.child[2].child[1].child[3].text
..
end loop

right or wrong, is it important? I think not
