This works as expected (it keeps the comments): 
use warnings;
use strict;
use XML::Twig;

my $str = <<EOF;
<foo>

    <!-- hello comment -->

    <bar>goo</bar>

</foo> 
EOF

my $t = XML::Twig->new(comments => 'keep');
$t->parse($str);
$t->print();
print "\n";

__END__

<foo>

    <!-- hello comment -->

    <bar>goo</bar></foo>

Try to create a small example like this that anyone can run which still demonstrates the problem.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
