| re: validating against schema with namespaces
The XmlValidatingReader can validate xml files against XDR schemas. You
should add your XDR schemas to the Schemas property of XmlValidatingReader.
"urn:schemas-microsoft-com:xml-data" and
"urn:schemas-microsoft-com:datatypes" will be understood implicitly but you
need to provide the XDR schema for "urn:schemas-microsoft-com:BizTalkServer"
namespace since it is a custom namespace that the XDR schema parser cannot
understand.
Sample code:
XmlTextReader tr = new XmlTextReader(url);
XmlValidatingReader vr = new XmlValidatingReader(tr);
vr.ValidationType = ValidationType.XDR;
vr.Schemas.Add("urn:schemas-microsoft-com:BizTalkServer",
"BiztalkXDRSchema.xdr");
vr.Schemas.Add("myNS","myXdrSchema.xdr");
vr.ValidationEventHandler += new ValidationEventHandler(ValidationCallback);
//Validate
while(vr.Read()) {
}
