Re: [MacPerl] Accessing Hash with Value

[Paul Wayne Rodney <pwrodney@mt-muse.com>]

You could do something like this:

 foreach $key (sort sort_by_value keys %hash) {
   print "$key has $hash{$key}  votes";}

where sort_by_values is a subroutine sorting by values (for instance, 
something like $hash{$a} <=> %hash{$b}).

cheers,
Paul
