Hi all,

I am attempting to create a multidimensional hash whose keys are the elements of a list. Simply put, I am parsing strings from a file and splitting them into key/val pairs on the '=' character. Then, I split the key itself on the ':' character, and would like to assign the result(s) as keys to a multidimensional hash.

Example:

The string/line read in from the file is 'a1:a2:a3=foo' - as a result, 'a1:a2:a3=foo' is assigned to $_ 

# $key = 'a1:a2:a3', $val = 'foo'
my ($key, $val) = split(/=/);

# find the number of ':' in string
my $num = map(/:/g, $key) + 1;

# create hash keys - split returns 'a1','a2', and 'a3'
# hash key creation NOT WORKING
%hash = split(/:/, $key, $num);

I'd like to create and assign $hash{'a1'}{'a2'}{'a3'} = 'foo'.

In case you're wondering, I find the number of ':' because this code is used in a loop, and each line may or may not vary with each loop iteration. The last split creates the keys, I just can't figure out the creation and assignment to the hash. I looked at map(), but have yet to come up with a solution.

Thanks for any help provided.
