Easy Hash to XML and back conversion in Ruby

Instead of spending hours trying to write something custom to convert your hash into xml or vice versa, you can do it in one line. If you are already in a Rails environment, you are good to go, but if using ruby, include the ActiveSupport gem:

require 'rubygems'
require 'active_support'

Now that you have, we can convert a xml to a hash:

hash = Hash.from_xml(xml_stream)

And a hash to xml is stupid simple:

xml = hash.to_xml

There you have it, simple xml to hash and hash to xml!
