I have a list of key words that I wish to insert elements for into an existing XML document. What I have so far is:

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

my @keywords = qw(this that the other);
my $twig = XML::Twig->new (
        pretty_print => 'indented',
        discard_spaces => 1,
        keep_encoding => 1,
    );

$twig->parse (do {local $/; <DATA>});

my $topic = $twig->root ();
my @newElts;
push @newElts, [keyword => {translate => 'true'}, $_] for @keywords;

my $keywordsElt = XML::Twig::Elt->new (keywords => {}, @newElts);

$keywordsElt->paste (first_child => $topic);
print $twig->sprint ();


__DATA__
<?xml version="1.0" encoding="UTF-8"?>
<topic>
  <body>
  </body>
</topic>

which prints:

<?xml version="1.0" encoding="UTF-8"?>
<topic>
  <keywords>ARRAY(0x1fa77a8)ARRAY(0x1fa77e4)ARRAY(0x1fa7850)ARRAY(0x1f
+a788c)</keywords>
  <body></body>
</topic>

[download]

but what I'd like is:

<?xml version="1.0" encoding="UTF-8"?>
<topic>
  <keywords>
    <keyword translate='true'>this</keyword>
    <keyword translate='true'>that</keyword>
    <keyword translate='true'>the</keyword>
    <keyword translate='true'>other</keyword>
  </keywords>
  <body></body>
</topic>

[download]

What am I missing?
