Hello monks,

Most of the time i parse data results from various system commands, consolidate everything into One Big Hash and then build from it various things i need, mostly other system commands. Sometimes it gets a little messy, and right now i have this structure : 

      'host1' => {
                          'tgt' => {
                                     'target_0011' => {
                                                     '11C3' => '0C5C',
                                                     '039F' => '14C4',
                                                     '11D3' => '0C6C',
                                                     '11F3' => '0C8C',
                                                     '11B3' => '0C4C',
                                                     '11E3' => '0C7C'
                                                   }
                                   },
                          'wwn' => [
                                     '10000000c95ffff1',
                                     '10000000c96ffff2'
                                   ]
                        },

Right now i only have one 'tgt' but it could change, so i end up doing : 
foreach my $host (keys %rez) {
foreach my $tgt ( keys %{ $rez{$host}{'tgt'} } ) {
foreach my $dev ( keys %{ $rez{$host}{'tgt'}{$tgt} } ) {

do something with $tgt, $dev and $rez{$host}{'tgt'}{$tgt}{$dev} 

}}}

Those 3 foreach, y'know, i don't like it :P
Is there a better way to do this ? Possibly something completely different ?

Thanks !
