Subject: Re: simple noob hash w/ arrays for values question

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?
