Hi Rob, Tying up the hash is done fantastically with the Tie::IxHash module. But when I pass the this tied hash to the XML::Simple it no more follow the tie for the hash. I am trying to get the XML nodes in the sequence which I am following to create the hash elements. Following is the sample code and the output which I am trying to get correct result. If I am missing somewhere please suggest. 
use strict;
use XML::Simple;
use Data::Dumper;
use Tie::IxHash;

my     $Request_data = {};

tie my %NewOrder_data , 'Tie::IxHash';

 %NewOrder_data =  (        
                    'IndustryType'        => ['EC'], 
                    'CurrencyCode'        => ['840'],
                    'CurrencyExponent1'    => ['1'],
                    'CurrencyExponent2'    => ['2'],
                    );



my @keys = keys %NewOrder_data;
print "\n@keys\n";

    my $xmlDS = {
        Request => [
                {                
                NewOrder => [
                                {
                                %NewOrder_data,
                                }
                            ],
                    }
            ],
        };



my $request_xml = eval {
    my $xs = new XML::Simple(keeproot => 1, SuppressEmpty => 1);
    $xs->XMLout($xmlDS);
    };

print STDERR "\n\nxml :- >\n" . Dumper($request_xml);


__END__

OUTPUT  :------->


IndustryType CurrencyCode CurrencyExponent1 CurrencyExponent2


xml :- >
<Request>
  <NewOrder1>
    <CurrencyCode>840</CurrencyCode>
    <CurrencyExponent2>2</CurrencyExponent2>
    <IndustryType>EC</IndustryType>
    <CurrencyExponent1>1</CurrencyExponent1>
  </NewOrder1>
</Request>
