Subject: How do I recursively traverse a data structure containing a mix of types?

For starters, I'm a total ruby noob who needs to be able to structure
the input data in such a way that it can be accessed & structured
sensibly.
I found an example on here that I've modified to the best of my
ability..but it does not do what I want.
The attached input file contains a real-life piece of data.

Here is the recursive function: I appreciate anyone who'd take a stab at
this.

def strip_hash_values(hash)

 #hash.each_value do |v|
  hash.each do |v|
    puts " strip_hash_values -- >"
    case v
      when String then puts "STRING #{v}"
        #v.strip!
        puts "<--strip_hash_values"
        return v
      #when Array  then strip_array_values(v)# i.strip!}
      when Array  then v.each {|i| #puts #Z"ARRAY value: #{i}"
       strip_hash_values(v)} # i.strip!}
      when Hash   then strip_hash_values(v)
      when Integer then puts "Integer #{v}"
        puts "<--strip_hash_values"
        return v
      else raise ArgumentError, "Unhandled type #{v.class}"
    end
  end
end
