I modified the input to consolidate the information, but the same concept applies:

use warnings;
use strict;
use XML::Twig;

undef $/;
my $XML = <DATA>;

open my $OUT, '>', '/tmp/twig_out' or die "Can't open file: $!";

my $twig = XML::Twig->new(
    twig_handlers => {
        name => sub {
            ### If you want the text.
            if (1) {
                print $OUT $_->text(), "\n";
            }
            ### If you want the elements.
            else {
                $_->print($OUT);
            }
        }
    }
);
$twig->parse($XML);

close $OUT or die $!;
