Here is the XML Data dumped using the Data Dumper.

$VAR1 = {
          'Dev' : {
                     'NM' : {
                               'nmsAc' : 'Unknown',
                               'nmsA' : '0.0.0.0:0'
                            },
                     'eve' : {
                               'alert' : '1',
                               'debug' : '1'
                             },
                        'Com' : {
                                  'cost' : '1',
                                  'stre' : 'nco',
                                },
                        'VeCog' : {
                                    'Operations' : {
                                            'A' : {
                                                    'Value' : '1',

                                             },
                                            'B' : {
                                                    'Value' : '10',
                                                    'Desc' : 'Minmess'
                                             },
                                            'C' : {
                                                    'Value' : '100',
                                                    'Desc' : 'Minmess'
                                             },
                                            'D' : {
                                                    'Value' : '1000',
                                                    'Desc' : 'Minmess'
                                             },
                                     }
                                     'disc' : {
                                         'con' : '0.0.0.0:0',
                                         'int' : 'None'
                                     }
                        }
            }

Here is my Perl Code

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

$xml = new XML::Simple;

$data = $xml->XMLin("/home/nager.xml");

print "$data->{Dev}->{VeCog}->{Operations}->{C}->{Value}\n";

I can print the value of element C with the print statement but I cant get the names of the elements A, B, C and D under the Element Operations. I want to be able to print the Key value pairs like

A:1
B:10
C:100
D:1000

How do I do that.
