Hi,

I am trying to add attributes to a tag as per my requirement. But in the result It is not in the same order as I added attributes. Please let me know how can I add attributes and get the result in the same order. My code is as below. Thank you in advance.

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

my $tagname="ait:date-delivered";
my $att1="month";
my $att2="year";
my $att3="day";

changeTagAttrOrder();

sub changeTagAttrOrder {
  my $t= XML::Twig->new(
            output_filter=>'safe',
            twig_handlers => { 
                               '_default_' => sub { },
                               *[@att='type'] => \&changeTagAttrOrderH
+andler;
                             },
                        pretty_print => 'indented',    
            keep_atts_order => 1,#Tie::IxHash needs to be installed fo
+r this option to be available. 
            );            
            $t->parse(\*DATA); 
            $t->print;
            $t->purge;
}#end of changeTagAttrOrder

sub changeTagAttrOrderHandler
{     
    my( $t,$rootElt)= @_;
    my $curEltPath = $rootElt->path;
    if($curEltPath =~ m/$tagname/){
        print "Found tag $tagname in path $curEltPath\n";
        print $rootElt->att($att1)."\t".$rootElt->att($att2)."\t".$roo
+tElt->att($att3);
        my $att1Val=$rootElt->att($att1);
        my $att2Val=$rootElt->att($att2);
        my $att3Val=$rootElt->att($att3);
        $rootElt->del_atts;
        print "after delete  \tAttributes are ::".join(",",$rootElt->a
+tt_names())."\n";
        $rootElt->set_atts( { $att1 => $att1Val, $att2 => $att2Val, $a
+tt3 => $att3Val});
        print "after new set \tAttributes are ::".join(",",$rootElt->a
+tt_names())."\n";
    }
}#end of changeTagAttrOrderHandler
