Try this

XmlDocument doc = new XmlDocument();
doc.Load("filename.xml");
XmlNodeList nodelist = doc.SelectNodes("employee");
if (nodelist[0].Attributes["Id"].Value == "5")
  {
     nodelist[0].Attributes["ChatStatus"].Value = "1";
     doc.Save("filename.xml");
  }

This will update the first node,if you want you can loop through the nodes.
