in thread accessing a hash of hashes
Thanks for the reply, that would work for my example, but I should have explained that I don't actually know the value of ID all the time, so infact my structure might look more like this:
$urls{'networkid'}{'someidIdontknow'}='somevalue1'; $urls{'networkid2'}{'someidIdontknow2'}='somevalue2'; $urls{'networkid3'}{'someidIdontknow3'}='somevalue3';
So unfortunately I can't access the value I don't know directly, but need a means to loop through all the values.
From looking at the post above I now have this code but it doesn't work.
foreach my $network (keys %urls) { foreach my $key (keys %$network) { print "$key<br/>"; } }
Any ideas where i'm going wrong? I know it's something to do with accessing the hashref.
Cheers, Tom
