Hi Monks, I am having a dumper value as follows

$VAR1 = {
          'nodeId' => '1234',
          'param' => {
                     'CardNumber' => '0000000000000000',
                     'Y' => '2000',
                     'M' => '06',
                     'C' => '000',
                   },
          'cont' => '0'
        };

And i need to chage the CardNumber value as 'XXXXXXXXXXXXXXXX' only during the printing of debug.
