how to serialize an xml node

I would like to transform an xml node into a RoR model but I don't
know how to start ..
I started using Nokogiri ( easy for newbie to get simple needs ...
but this one is more complex for my current level of understanding ...
xml node :

       <localized>
             <locale>
                 <code>en_GB</code>
                 <title>Special Team</title>
                 <description>Academy Guests</description>
              </locale>

    <locale>
                <code>en_US</code>
      ……..
    </locale>

    <locale>
                <code>es</code>
      ……..
    </locale>
        </localized>

I defined in my model : serialize :localized, Array

I should get an Array of Hash to be serialized
[ {:code => "en_GB", :title => "Special Team", :description =>
"Academy Guest"}, {:code => "en_US", :title => ….. } , {:code =>
"es", :title => ….. } ]

how should I proceed or look for info ..
thanks for your help
