Subject: Hash to_xml from_xml

Am I missing something

    require 'active_record'
    require 'active_support'
    require 'pp'

    v = Hash.from_xml %{
    <hash>
      <users type="array">
          <user type="integer">1</user>
          <user type="integer">2</user>
          <user type="integer">3</user>
      </users>
    </hash>
    }
    pp v
    pp v.to_xml

generates

    {"hash"=>{"users"=>[1, 2, 3]}}

Any way to get this working?
