Iterating over a hash map

Hello, I'm trying to iterate over a hash map I created, but its not working very well... I've been experimenting in IRB like so:

compare_hash = {} compare_hash["item1"] = ["subitem1","subitem2"] compare_hash["item2"] = ["subitem1","subitem2"]

compare_hash.each do |item| puts item[0] end

instead of giving me the expected results of: subitem1 subitem2

it gives me only the names: item1 item2

Does anybody know how to do this properly?

Thanks! - Jeff Miller

compare_hash.each do |key, value|    puts key #will output item1, item2    puts value #will out put the values end
