Yes, clients parse the XML and put it into some data structure that is
appropriate for the language. Some client languages support object some
don't. The data comes in a standard data structure in XML. SOAP use XML
Schema so data typing is standardized. With MS you need to either write
deserializers or extract what you want from the raw XML. Check the MS
toolkit docs on this.
