Subject: matching regular expression

I have a string that contains a list of keys and values.

"key1: a_value, key2: another_value, key3: yet_another_value"

I have an array of ["key1", "key2", "key3"].

I'd like to loop through and find all the values in the string that
have a key in the key array.

My first attempt was:

keys = ["key1", "key2", "key3"]
my_str = "key1: a_value, key2: another_value, key3: yet_another_value"
keys.each do |key|
    my_str =~ Regexp.new("#{key}: \\w+")
    puts "the value for #{key} was #{$1}"
end

But that's not working properly.

Any ideas?

Thanks,
Joe
