  dosomat($mech->content);
  my $next = $mech->find_link( text_regex => qr/Next$/, url_regex => q
+r/^\/search\?/) or die("finished on page : ".$i."\n");
  $mech->get($url.$next->url);
}

exit(0);


sub dosomat {
  my ($content) = @_;
  my @cont = $content =~ m{<div class=g(.*?)</div>}gsi;

  for my $i (0..$#cont) {
    print $cont[$i]."\n\n\n";
  }
