I need to validate a Perl hash of hash element such as $Table{$key1}{$key2} exist and defined. Here is what i do. (i have no idea key1 even exist)
if
((defined $Table{$key1}) &&
(exists $Table{$key1}) &&
(defined $Table{$key1}{$key2}) &&
(exists $Table{$key1}{$key2}))
{
#do whatever
}
Is there an easier and cleaner way to do it?
