Hi,
I'm wondering if there's an easier way to get the sizes of hash elements which are also hashes.

IE:
INPUT FORMAT Volume-Chapter-Section-Item (value):
B-001-01-01 (2)
...
B-999-99-99 (x)

while (<>) {
    if (/^(\w{1})\-(\d{3})\-(\d{1,2})\-(\d{1,2})\s+\((\d+)\)/) {
#        print "$1, $2, $3, $4, $5\n";
        $hash{$1}{$2}{$3}{$4} = $5;
    }
}

I'm trying to find how many Items in a Section,
How many Sections in a Chapter,
How many Chapters in a Volume.
Is there an easier way?

I know that I can get the number of volume by using "scalar keys %hash", but how do I drill down?

TIA
