Hello,
I need to call a webservice with an
System.Xml.XmlD ocument objet and read the return value into and
System.Xml.XmlD ocument. The webservice was written with an oracle tool and
wrapped into a .net webservice.
I have added a reference to my dotnet wrapper and i get the following

JJ,
I have noticed that attempting to return an XmlDocument from an ASP.NET
Webservice usually results in getting an XmlNode. So you can try getting the
result of the WebService Call as XmlNode, and if you really require a
complete XmlDocument, just add the Node to a new instance of XmlDocument.

Many thanks Peter,
Well i was very unsure how to go from XmlNode to XmlDocument.
I have now been through a couple msdn pages and it now makes more sens to me
thanks to your posting.
