Thanks wind, Please have a look at this

use XML::Simple;
use strict;
use warnings;

my ($id, $value);

#group 1 paramters 
$id = "ID1";
$value = "Recording INformation";
getParameter($id, $value);
$id = "ID2";
$value = "Pausing INformation Record ";
getParameter($id, $value);
$value = "Information Loading";
getParameter($id, $value);
$value = "Information loading Complete";

#From here group 2 parameter starts
my $id = 2;
$value = "Picture loading";
getParameter($id, $value);
my $id = 3;
$value = "Picture loading complete";
getParameter($id, $value);
#Group 2 parameters end.

sub getParameter

{
    my ( $id,$value) = @_;
    my $hash = {
        'Key' => $id,
        'Value' => $value
    };

my $xml = { Parameter => [] };
push( @{ $xml->{Parameter} }
    , { key => $hash->{Key}, content => $hash->{Value} }
    );
    
    print XMLout( $xml, RootName => 'Parameter' );

}

Right now, the output that i get is something like

 <Parameter key="ID1">Recording INformation</Parameter>
 <Parameter key="ID2">Pausing INformation Record</Parameter>
 <Parameter key="ID2">Information Loading</Parameter>
 <Parameter key="ID2">Information loading Complete</Parameter>

If I need something like

<Parameters>
- <ParameterGroup ID="Group1">
  <Parameter key="Key1">Some Value</Parameter> 
  <Parameter key="Key2">Some Value</Parameter> 
  <Parameter key="Key3">Some Value</Parameter> 
  </ParameterGroup>
- <ParameterGroup ID="Group2">
  <Parameter key="Key1">Some Value</Parameter> 
  <Parameter key="Key2">Some Value</Parameter> 
  <Parameter key="Key3">Some Value</Parameter> 
  </ParameterGroup>
  </Parameters>

What do I have to do? Thanks
