A hash of hashes (HoH)

#! /usr/perl/bin

use warnings;
use strict;
use Data::Dumper;

my $abc = {
  one => {
    oneone => 11,
    onetwo => 12,
  },
  two => {
    twoone => 21,
    twotwo => 22,
  }
};

foreach my $key (keys %{$abc}) {
    if ( ref $abc->{$key} eq 'HASH' ) {
      for my $subkey (keys %{$abc->{$key}}){
        printf qq{%s -> %s\n}, $subkey, $abc->{$key}{$subkey};
      }
    }

Thanks for the replies. I actually figured this out moments after the post. Is it possible to delete my own posts?	[reply]

The post is doing no harm. It might help other users searching on this site for helpful threads. You can edit your posts, but if you remove the text the answers to your post would hang there without meaning	[reply]

Additionally, if you do edit your content to a point where the meaning is lost or later posts become nonsensical, there will likely be a consideration request to restore the content. --MidLifeXis	[reply]
