Overwrite XML data directly using VTD-XML

// description of your code here
// This example shows you how to overwrite a token using
// VTDNav's overwrite method call
// The basic concept is that if the replacement value is
// shorter than the original token, then you can directly
// write the replacement bytes into the XML message and
// the original VTD structure doesn't change at all!!!

			//overwrite, if successful, returns true

			//print "bad" here
