Rails XML parsing

Can anybody tell me how to parse this on rails.

<?xml version="1.0" encoding="utf-8"?>
<message>
  <param>
    <name>messageType</name>
    <value>SMS</value>
  </param>
  <param>
    <name>id</name>
    <value>xxxxxxxxxxxxxx</value>
  </param>
  <param>
    <name>source</name>
    <value>xxxxxxxxxxx</value>
  </param>
  <param>
    <name>target</name>
    <value>xxxxxxxxxxxxx</value>
  </param>
  <param>
    <name>msg</name>
    <value>xxxxxxxxxxxxx</value>
  </param>
  <param>
    <name>udh</name>
    <value></value>
  </param>
</message>

I have no control on this xml, but I hope I can make the parameter looks like this before saving to my database

message"=>{"msg"=>"sampler", "id"=>"1", "target"=>"23123", "source"=>"312321312"}

here is the parameter I received when it access my method

message"=>{"param"=>[{"name"=>"id", "value"=>"2373084120100804002252"}, {"name"=>"messageType", "value"=>"SMS"}, {"name"=>"target", "value"=>"23730841"}, {"name"=>"source", "value"=>"09156490046"}, {"name"=>"msg", "value"=>"Hello world via iPhone"}, {"name"=>"udh", "value"=>nil}]}
