simple noob hash w/ arrays for values question

snowball

Sorry for the simple question, but I'm new to programming and have been
banging my head over this.

I've got myself a hash with each value an array of strings. I want to
grep the strings and collect only the strings that match the regexp
into an array. How do I go about this?

my_result_array = []
my_hash.each_value do |my_array|
my_result_array += my_array.select { |item| item =~ /^[A-Za-z]+$/ }
end

The code above would go through and put all of the strings that only
consisted of letters into one array. Is something like this what you
were looking for?

my_array = my_hash.values.flatten.select{|s| s =~ /.../}
