Estemed monks,

I have an XML document which I parse using XML::Simple, I then try to modify it and then output it again as a string using XML::Simple. But the structure changes subtly and I am at a loss as to what I need to do: 

#!/usr/bin/perl -w
use strict;

use XML::Simple;
use Data::Dumper;

my $self;
my $pr_no_attach_xml;

$pr_no_attach_xml = qq~<?xml version="1.0" encoding="UTF-8" ?>
<voice_broadcast_info xmlns="http://www.obfuscated.com" xmlns:xsi="htt
+p://www.w3.org/2001/XMLSchema-instance">

   <login_key>

   <voice_broadcast_options>

      <delivery_type>both</delivery_type>

   </voice_broadcast_options>
   <voice_recipient_list>
      <voice_recipient>
         <voice_recipient_number>1AREACODENUMBER</voice_recipient_numb

      </voice_recipient>

         <voice_recipient_reference>bc-voice-2</voice_recipient_refere

      </voice_recipient>
   </voice_recipient_list>   
   <voice_answer_file vcast_file_content_type="audio/wav" vcast_file_e

</voice_broadcast_info>~;

my $xs = XML::Simple->new(
  KeepRoot => 1,
  GroupTags => { voice_recipient_list => 'voice_recipient' },
  KeyAttr   => [ 'name' ],
);

  $self->{_upload_hash} = $xs->XMLin( $pr_no_attach_xml );
  print Dumper $self->{_upload_hash};
  
# Now modify the XML a little:
  $self->{_upload_hash}->{voice_broadcast_info}->{voice_recipient_list
+} = [
    {
      'voice_recipient' => {
        'voice_recipient_number'    => '14169999999',
        'voice_recipient_name'      => 'John Day - 1',
        'voice_recipient_reference' => 'bc-voice-1'
      }
    },
    {
      'voice_recipient' => {
        'voice_recipient_number'    => '14169999999',
        'voice_recipient_name'      => 'John Day - 2',
        'voice_recipient_reference' => 'bc-voice-1'
      }
    }

  ];

  my $xml = $xs->XMLout( $self->{_upload_hash}, attrIndent => 1 );

  print "\nThrough the pipe - XML::Simple :\n\n$xml\n";

As you can see the output is not the same as the input! WHat I need is XML like this:
   <voice_recipient_list>
      <voice_recipient>
         <voice_recipient_number>1AREACODENUMBER</voice_recipient_numb
+er>
         <voice_recipient_name>Me</voice_recipient_name>
         <voice_recipient_reference>bc-voice-1</voice_recipient_refere
+nce>
      </voice_recipient>

Rather than like this:
    <voice_recipient name="voice_recipient"
                     voice_recipient_name="John Day - 1"
                     voice_recipient_number="14167781583"
                     voice_recipient_reference="bc-voice-1" />

Where am I going wrong? Thanks, jdtoronto
