Hello Monks - I have read over perlreftut and perldsc enough times to get through most of my issues - but I'm now experiencing a problem I can't get past: Below is an example Data Dumper output. 

$VAR1 = {
          'somethingunknown' => [
                                            {
                                              'attachedto' => 'Server1
+',
                                              'val2' => 'x.x.x.x',
                                              'expires' => '7',
                                            },
                                            {
                                              'attachedto' => undef,
                                              'val2' => 'x.x.x.x',
                                              'expires' => '7',
                                            },
                                          ]
        };

$VAR1 = {
          'someothername' => [
                                      {
                                        'attachedto' => 'server4',
                                        'val2', => 'xyz',
                                        'expires' => '24'
                                      }
                                    ]
        };

My problem is, I would typically access data using something like

print $element->{'somethingunknown'}[0]{'val2'}";

While I'm using a loop how do I know that what I'm looking for is $element->{'somethingunknown'} vs $element->{'someothername'}. Any help would be much appreciated. Everything I've tried to do to access the actual name of the value just gives me errors, either telling me it's a hash or I can't splice an array that way etc.
