It seems to me that for each element of the appropriate level, you want to output the entire tree, including the element, then delete the element so when you get to the next element you get a "clean" tree.

The code below gives you the output you want:

#!/usr/local/bin/perl -w

use strict;
use XML::Twig;

my $xml_twig = XML::Twig->new(
    pretty_print => 'indented',
    NoLWP => 1,
    discard_spaces => 1,
    twig_handlers => { 'level(1)' => \&dump_partial_tree }
);

$xml_twig->parse ( \*DATA ) || die "\nError parsing data $@\n";


sub dump_partial_tree
  { my( $xml_twig, $element)= @_;
    print "\n\nName : " . $element->name . "\n";
    $xml_twig->print;
    print "\n";
    $element->delete;
}

__DATA__
<myconfig_data>
        <level1>
                <tag>hello1</tag>
        </level1>
        <level2>
                <tag>hello2</tag>
        </level2>
        <level3>
                <tag>hello3</tag>
        </level3>
</myconfig_data>
