Perl :: reading values from Data Dumper reference in Perl

Hi all,

I have written a perl code and stored the data into Data structure using Data:Smilieumper module.
But not sure how to retreive the data from the Data:Smilieumper.

Eg.

Based on the key value( Here CRYPTO-6-IKMP_MODE_FAILURE I should be able to access the internal hash elements(keys) template and regex.

Could anyone please let me know how to access the inner elements from DataDumper reference.

Tons of thanks...!!!



Code:
$VAR1 = {
          'CRYPTO-6-IKMP_MODE_FAILURE' => [
                                            {
                                              'template' => 'Processing of Informational mode failed with peer',
                                              'regex' => 'Processing of Informational mode failed with peer at d{1,3}.d{1,3}.d{1,3}.d{1,3}'
                                            }
                                          ],

Assuming that your hash (data structure) is named %data, you can access "template" using:
Code:
$data{'CRYPTO-6-IKMP_MODE_FAILURE'}[0]{'template'}

And "regex":
Code:
$data{'CRYPTO-6-IKMP_MODE_FAILURE'}[0]{'regex'}
