pg, I don't think that does the trick either. See my response. Try dumping that structure ... you'll get something like this:

$VAR1 = {
          'component1' => {
                            'ARRAY(0x816936c)' => [
                                                    'name',
                                                    'command4',
                                                    'id',
                                                    '004'
                                                  ],
                            'ARRAY(0x813bf00)' => [
                                                    'name',
                                                    'command2',
                                                    'id',
                                                    '002'
                                                  ]
                          },
