With ruby you could use REXML's Hash.from_xml, but I really don't like that. The reason for me to write this, was to convert various xml responses from different soap services to a hash. I don't want any namespaces, attributes, etc. Here's an example response:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns2:authenticateResponse xmlns:ns2="http://v1_0.ws.some.namespace/">
<return>
<authenticationValue>
<orderToken>dfgdfg-4356345-sdfsdf-2345234-234</orderToken>
<tokenHash>000111DDD888444777NNNZZZ555000</tokenHash>
<client>dude</client>
</authenticationValue>
<success>true</success>
</return>
</ns2:authenticateResponse>
</soap:Body>
</soap:Envelope>
