Getting last element of an xml file

[jambo310]

let say i have the following xml file\[code\]<Users> <User> <Name>David</Name> <Date>9/30/2012 10:52:00 PM</Date> </User> <User> <Name>David</Name> <Date>9/30/2012 11:02:05 PM</Date> </User> <User> <Name>David</Name> <Date>9/30/2012 11:52:00 PM</Date> </User> <User> <Name>Michelle</Name> <Date>9/30/2012 11:02:13 PM</Date> </User> <User> <Name>Michelle</Name> <Date>9/30/2012 11:02:54 PM</Date> </User></Users>\[/code\]I will like to read the last date of David and put it on a string in my C# program, in this case it will be "9/30/2012 11:52:00 PM" I have the following code which is suppose to read the date of a particular User, but it is not working\[code\] public void readLastDate(string name) { string filePaths = "logins.xml"; XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(filePaths); xmlDoc.DocumentElement.SetAttribute("searching",name); XmlNodeList tests = xmlDoc.SelectNodes("//Users[Name =/*/@searching]/User"); foreach (XmlNode test in tests) { string myDate = test.SelectSingleNode("LoginDate").InnerText; InfoBox.Items.Add("Last Date:" + myDate); } \[/code\]Also, how would i handle an error if i want to read a date of a user that is not in the xml file. }
