How do I get this element :o)

[Don Stewart <Do...@corizon.com>]

Given the following SOAP Envelope :-
 
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soapenv:Body>
        <loginResponse xmlns="urn:partner.soap.sforce.com">
            <result>
                <passwordExpired>false</passwordExpired>
 
<serverUrl>https://na1-api.salesforce.com/services/Soap/u/5.0</serverUrl
>
 
<sessionId>4evpgJR1YdvlFc5LU0pE2.jPLX9qmf2NEW_h.RjwQM3.zUsbhMnl6XgVW4Ph5
FTNsgq3oAODeA_yyDR07EVUhzteaH1xyGi1</sessionId>
                <userId>00530000000euXxAAI</userId>
            </result>
        </loginResponse>
    </soapenv:Body>
</soapenv:Envelope>
 
I need to select the <login response>. Howerver, this redefines
(actually defines for the first time) the default namespace, and it's a
urn.
Using XmlBeans V2.x and Saxon what would the XPath expression be?
 
I have tried all I can think of but it eludes me as it's a urn.
 
I have had success with 
 
lEnvelopeDoc.getEnvelope().getBody().selectChildren("urn:partner.soap.sf
orce.com", "loginResponse");
 
but this restures the contents and not the actual LoginResponseDocument
so I am trying to get the equiq. selectPath somthing like (but I know
not this is not correct) :-
 
lEnvelopeDoc.getEnvelope().getBody().selectPath("//urn:partner.soap.sfor
ce.com:loginResponse");
 
Many Thanks
 
Don
