The following code example demonstrates how to use UnescapedXmlDiagnosticData class. This code example is part of a larger example that is provided for the EventSchemaTraceListener class.

string testString = "<Test><InnerElement Val=\"1\" /><InnerElement Val=\"Data\"/><AnotherElement>11</AnotherElement></Test>";
UnescapedXmlDiagnosticData unXData = new UnescapedXmlDiagnosticData(testString);
ts.TraceData(TraceEventType.Error, 38, unXData);
