I'm getting funny results. Don't know how it can happen. I'm updating the xml. Open output file. Using new technique to pass extra args to twig handlers. Passing the filehandle to twig handler, and to twig_print_outside_roots.

It all works, except I put a debug print statement in the handler. It prints to STDOUT, but it doesn't go there, it goes into the output xml.

Here's a code snippet:

open(OUT, ">$tmpdir/$fname")
    or die "Can't open output $tmpdir/$fname: $!\n";

my $twig = XML::Twig->new(twig_roots => {
           '/object/attributes/attribute' =>
                    sub { put_new_jump(@_, \*OUT, $path) },
           },
            twig_print_outside_roots => \*OUT,
            keep_encoding => 1,
);



sub put_new_jump {
    my ($tree, $elem, $fh, $path) = @_;

    my $name = $elem->att('name');

    print "Name:  $name\n";
<blah blah blah>
    $elem->print($fh);
}

See that 'print_outside_roots => \*OUT' works, and $elem->print($fh) works. But why is STDOUT also being redirected into the xml? Oh, here's what part of the xml looks like: 
      Name:  CreateTime
<attribute group="Graph" kind="integer" name="CreateTime">1250716389</
+attribute>
      Name:  RevOperator
<attribute group="Graph" kind="string" name="RevOperator">jwalton</att
+ribute>
      Name:  Uid
<attribute group="Graph" kind="string" name="Uid">PS4PS9S</attribute>
      Name:  DataRevisionDate
<attribute group="Graph" kind="integer" name="DataRevisionDate">125080
+1191</attribute>
