You have to parse the XML to get the data out of it. You could use a DOM or a SAX parser, but since this is a SOAP message, I would rather use a SOAP based library that does the translation between SOAP messages to Java objects and vice versa. Have a look at the Apache CXF library. There might be even simpler ones.
