I made the code to run but it doesn't work :)

I mean that it doesn't do what it's suppose to do, this is the output:

after delete
            Attributes are: 
after new set
            Attributes are: day,month,year
<item>
...
    <ait:date-delivered month="02" day="09" year="2010"/>
...
</item>

It's funny but the order is different for all tree steps, in the original doc, aftet delete and insert an in the resulting doc.

On the other hand the man page say:
'keep_atts_order' allows outputting the attributes in the same order as they were in the original document.

Does this mean XML::Twig it's not designed to work this way?

#!/usr/bin/perl
use strict;
use warnings;
use XML::Twig;

changeTagAttrOrder();

sub changeTagAttrOrder {
    my $t = XML::Twig->new(
        output_filter=>'safe',
        twig_handlers => {
            'ait:date-delivered' => \&changeTagAttrOrderHandler,
        },
        pretty_print => 'indented',
        keep_atts_order => 1,
    );
    $t->parse(\*DATA);
    $t->print;
    $t->purge;
}#end of changeTagAttrOrder

sub changeTagAttrOrderHandler {
    my( $t,$rootElt)= @_;
    my $curEltPath = $rootElt->path;

    my $att1Val = $rootElt->att('month');
    my $att2Val = $rootElt->att('year');
    my $att3Val = $rootElt->att('day');

    $rootElt->del_atts;
    print "after delete\n
            Attributes are: ".join(',',$rootElt->att_names())."\n";
    # $rootElt->set_atts(
    #     { month => $att1Val, year => $att2Val, day => $att3Val});
    $rootElt->set_att(day   => $att3Val);
    $rootElt->set_att(month => $att1Val);
    $rootElt->set_att(year  => $att2Val);

    print "after new set\n
            Attributes are: ".join(',',$rootElt->att_names())."\n";
}#end of changeTagAttrOrderHandler

__DATA__
