Very sorry to keep bothering but I am not sure I understand.
For my project I have to consume a Webservice for Read operations (which has an XSLT) and another Webservice for UPDATE operations (this WS is created directly from a WSDL).
I am still not sure what you mean by "out <data> node". If you could be more specific, may-be with an example I would very much apreaciate it.
Best regards
