Unknown attribute detectedif (e.Attr.Name == "birthdate"){Employee emp = (Employee) e.ObjectBeingDeserialized;DateTime dt = DateTime.Parse(e.Attr.Value);emp.Age = (int) (DateTime.Now.Year - dt.Year);}Populating Collection PropertiesAn even more complex scenario arises when the source XML contains embedded data,the result of INNER JOIN operations being rendered in XML. Consider the followingstatement:SELECT firstname, lastname, title, hiredate, birthdate,terr.territorydescriptionFROM Employees As employeesINNER JOIN EmployeeTerritories AS empterrON employees.employeeid=empterr.employeeidINNER JOIN Territories AS terrON empterr.territoryid=terr.territoryidWHERE employees.employeeid=@empIDFOR XML AUTOThe XML output for the empID parameter that equals 1 is shown here:This output changes a little bit if you use the ELEMENTS clause, as follows:NancyDavolio...WiltonNewardThe application is always notified of any elements through an UnknownElementevent. Suppose you also want any territory description to populate a StringCollectionproperty in the Employee class. The following code shows how to handle the event andaccumulate the data for an unknown element in the string collection:if (e.Element.Name == "terr")415
