Greetings all,
Just another suggestion. I would turn %products into an array and then use the Schwartzian Transform to do the sorting.
untested suggestion
my @products ( { name => "Floor Wax", wholesale => "50.00", retail => "75.00", }, { name => "Paper Towel", wholesale => "20.00", retail => "40.00", }, { name => "Hand Soap", wholesale => "30.00", retail => "65.00", } ); my @sorted_by_name = map{$_->[1]} sort {$a->[0] cmp $b->[0]} map{[$_->{name},$_]} @products my @sorted_by_wholesale = map{$_->[1]} sort {$a->[0] <=> $b->[0]} map{[$_->{wholesale},$_]} @products
Hope that helps,
