Re: Hash of hashes question

First of all:

use strict;
use warnings;

This will save you a lot of time debugging.
This is how I would go about traversing your hash:

for my $key(keys %termservers)
{
    for my $key2(keys %{$termservers{$key}})
    {
        print "$key1 - $key2 = $termservers{$key1}{$key2}\n";
    }
}

Update:
If you don't already have it, and I'm guessing you don't, get the "Camel" book (Programming Perl). Chapter 9 discusses data structures in depth. This book is a must read for any perl programmer.

Though I would recommend the book, "perldoc perldsc" does a pretty good job as well, and then you don't have to wait to you can get a book (or get to a Camel book) to get the skinny on data structures. -enlil	[reply]

There's even a specific book on modules, references and objects, which I suspect is an edited and expanded version of the core documentation regarding those subjects. According to some reviews I've seen, it's pretty good. Arjen	[reply]
