Dear Monks,

I've been searching for a solution to write and read a variable number of hashes into hashes. So far I had no luck. Hope you guys can help me out!

So my data is something like this;

string1,string2,string3,string4
string3,string4
string1,string2,string3

I want each line into a hash of hashes of hashes... like this;

%hash{'string1'}{'string2'}{'string3'}{'string4'}++;
%hash{'string3'}{'string4'}++;
%hash{'string1'}{'string2'}{'string3'}++;

How can i fill this hash properly? Note, I do not know how many strings I can have in the array, so there even might be a string 'string1...string10'.

After I have filled it, how can I read it out? Normally i do it something like this;

foreach my $k1 (keys %hash){
  foreach my $k2 (keys %hash{$k1}){
...
  }
}

But then I know the number of hashes on beforehand.

Any advice would be great.

Thanks, Boetsie
