Hash of Hashes - Keys Count 1

[Extension]

Hi,

I have a hash of hashes and I would like to know how to do a quick count of the hash keys for the "second level".

For a simple hash, I'm doing this:

$KeysCount = keys %Hash;

But for a hash of hashes, if I do the same I will get a record count only for the "first level" of keys.

I woud like to avoid looping through the hash to get the record count.

to avoid looping you need to know the name(s) of the hash keys:

$n = keys %{ $Hash{key_name} };

otherwise you will have to loop through the first level hash:

my $n = 0;
foreach my $key (keys %Hash) {
   $n += keys %{$key}
}

- Kevin, perl coder unexceptional!

Thanks KevinADC. I guess I will have to loop through all the Hash keys.

Thank you
