Aha...I know what it is.

ReadSchema() has eight overloaded methods and none of them accepts String as XML..Try the following..

StringReader loStream = new StringReader(lcXML);
XmlTextReader loXmlTextReader = new XmlTextReader(loStream);
	
loDataSet.ReadXml((loXmlTextReader,XmlReadMode.ReadSchema);

loStream.Close();
loXmlTextReader.Close();

>I've changed added XmlReadMode.ReadSchema, but I am still getting the same error.

>>>I am getting the error "Invalid URI: The URI scheme is not valid." When I use ReadXML() into a dataset. I don't understand what the error means. Is the XML invalid? Any ideas what could be invalid about it?
