Re: How to address hashtables nested in arrays?

[pme]

Hi benedicth,

You can access the values this way:

foreach my $n (@{$data->{instance}}) {
  foreach my $m (@{$n->{contact}}) {
    foreach my $key (keys %{$m}) {
      print "key: $key -> $m->{$key}\n";
    }
  }
}

Thank you so much!! I'm still a newbie can you tell me why %{$data->{$m} does not work in this case?

In this case both $n and $m contain hash reference but in %{$data->{$m}} $m should be a key.

Try to run your script in perl debugger (perldebug) and check $n and $m using 'x' command for better understanding.
