Using:

XElement kd = XElement.Load(path);
kd.Add(new XElement("players",开发者_运维技巧
       new XAttribute("name", username),
       new XElement("kills", 0),
       new XElement("deaths", 0)));

Nothing is added to XML file:

<?xml version="1.0" encoding="utf-8"?>
<SimpleKD>
  <player name="Tardis">
    <kills>0</kills>
    <deaths>0</deaths>
    </player>
</SimpleKD>

Am I doing it wrong?
