Double Hash?

[mikerobb]

Hi-

I have a double hash and am trying to do a foreach (sort) on the inner hash.

This code doesn't want to work. Any ideas?


my $from_state,$to_state;
foreach $from_state (sort keys %rt::states) {
foreach $to_state (sort keys %rt::states{$from_state}) {

it bombs on the syntax of the 2nd foreach statement.

The hashes are valid and defined and work.
warn "$rt::states{'one'}{'two'}{'data'}";
^^^-- this will output the correct data that has been set into it.

Any ideas?

-TIA!

If my memory is correct I think you need another pair of braces {} around the hash in the second foreach:-

sort keys %{ rt::states{$from_state}}
