Thanks 2teez! I've one problem, my requirement is to integrate 'StateTax' tag in xml file which I'm creating using different files. I've got 2 hashes: 1st -> data having various fields which is to be added into xml file. Hash is like below:

$VAR1 = {
          'retailer-2247.txt.gz' => {
                                      'logo' => 'http://cfsi.pgcdn.com
+/images/retbutton_2247.gif',
                                      'mid' => '2247',
                                      'feedCount' => undef,
                                      'feedNumbers' => undef,
                                      'url' => 'http://tracking.search
+marketing.com',
                                      'merchant' => '1STOPlighting',
                                      'type' => 'CPC',
                                      'parentAccount' => undef,
                                      'feedName' => 'retailer-2247.txt
+.gz'
                                    }
     }

2nd -> tax info retrieved from a different file. Hash is like:

{
          '19428' => {
                       'rate' => [
                                   '7.000'
                                 ],
                       'state' => [
                                    'NJ'
                                  ]
                     },
          '2247' => {
                      'rate' => [
                                  '9.750',
                                  '7.000'
                                ],
                      'state' => [
                                   'IL',
                                   'IN'
                                 ]
                    }
}

So I need to merge the state info tag into xml file (comparison would be on mid i.e. 2247). Could anyone please help? And this question regarding the same I've asked earlier.

  <merchant id="2247">
    <name>1STOPlighting</name>
    <url>http://tracking.searchmarketing.com</url>
    <type>CPC</type>
    <logoUrl>http://cfsi.pgcdn.com/images/retbutton_2247.gif</logoUrl>
    <ntParentAcct>5403020</ntParentAcct>
    <feedCount>1</feedCount>
    <feedNumbers>1</feedNumbers>
    <StateTax>IL, IN</StateTax>
</code

PERL Code I've written, it's using XML::LibXML module to handle encodi
+ng cases.
