As Tanktalus mentioned, you cannot use ignore_elt for this.

An other way to do this is to set a twig handler on 'title/title/title' that will just return 0, this will prevent the handler on title to be run:

my $twig = XML::Twig->new( twig_handlers => { $ign => sub { return 0},
                                              $sel => \&title,
                                            },
