and for the read part:
doca = new XPathDocument(Application.StartupPath + @"\myfile.xml");
nav = doca.CreateNavigator();
expr = nav.Compile("/MySelectedValues");
iterator = nav.Select(expr);
while(iterator.MoveNext())
{
XPathNavigator nav2 = iterator.Current.Clone();
nav2.MoveToFirstChild();
string s1 = nav2.Value.ToString();
nav2.MoveToNext()
string s2 = nav2.Value.ToString;
