How to get SOAP body parameter

[YIXING MA]

Hi all,
I have the SOAPMessage as this
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<soapenv:Body wsu:Id="wsse-8b3900e0-c7e4-11d9-a50e-2f72ed6c1032" 
xmlns:wsu="http://schemas.xmlsoap.org/ws/2002/07/utility";>
 <ns1:service 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
xmlns:ns1="http://dataaccess.service.eTranscript.interfacemgmt.net";>

<xml xsi:type="xsd:string">
&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt;
&lt;CollegeTranscript 
xsi:schemaLocation="urn:org:pesc:message:CollegeTranscript:v1.0.0 
CollegeTranscript_v1.0.0.xsd" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns="urn:org:pesc:message:CollegeTranscript:v1.0.0"&gt;
   &lt;/CollegeTranscript&gt;
</xml>

 </ns1:service>
</soapenv:Body>
</soapenv:Envelope>
-------------------------------------------------------------------------------------------------------------------------------------------------------
I want to get the content of <xml xsi:type="xsd:string"> ... </xml>
<xml xsi:type="xsd:string">
&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt;
&lt;CollegeTranscript 
xsi:schemaLocation="urn:org:pesc:message:CollegeTranscript:v1.0.0 
CollegeTranscript_v1.0.0.xsd" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns="urn:org:pesc:message:CollegeTranscript:v1.0.0"&gt;
   &lt;/CollegeTranscript&gt;
</xml>

How to do that in Java?
Thanks,
