In playing around with code for a recent SoPW answer I got distracted by what seems to be a bug in XML::Twig. I updated to the current version and the problem seems to have changed somewhat (the "answer" code now works if a flush is removed), but there seems to be a related error:

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

my $org = <<XML;
<XXX>
</XXX>
XML

print "XML::Twig version $XML::Twig::VERSION\n";

my $twig = XML::Twig->new (
    twig_roots               => {'head' => \&editNode,},
    twig_print_outside_roots => 1
);

$twig->parse ($org);
$twig->flush ();


sub editNode {
    my ($t, $elt) = @_;

    $t->flush      ();
}

[download]

Prints:

XML::Twig version 3.32
<XXX>
</XXX>
</XXX>

[download]

Note the duplicated close tag. Removing the flush after the parse fixes the problem, but the documentation and samples mention in several places that it should be there.

Is it a bug? Should I report it?

Update reported as rt://39848.
