Hi monks, This is very simple for experts but not for beginners like me.I have one xml file and I processed using XML::Simple like this

my $file="service.xml";
 my $xml = new XML::Simple;
  my $data = $xml->XMLin("$file", ForceArray =>['Service','SystemReact
+ion','Customers','Suppliers','SW','HW'],);
print Dupmer ($data);

it printing hash of data like this

$var1={

  'Service' => [
                      
                {
                  'Suppliers' => [
                                  {

How to access each elements in the service and systemReaction(not provided). because I am using "$data" in further processing. So I need to access each Id,customers, suppliers values in each service. How to get particular value from service to do some process with that value.for example I need to get all Id values form service and create nodes for each id values.

Thanks in advance
