Joao,

I usually use a StringReader, as shown below. I don't know if this will solve your problem or not, but I suggest that you try it. Are you sure the cXML you get back from the Web Service call is well-formed XML?

Dim oSR As New System.IO.StringReader(cXML)
Dim oDS As New DataSet
oDS.ReadXml(oSR)
