This code works.  It prints out two values from the xml file like it should
reader = XmlReader.Create("c:\\test.xml");
      while (reader.ReadToFollowing("chapter"))
      {
        Console.WriteLine(reader.ReadInnerXml());
      }
      reader.Close();

This code only prints the value once and does not print the second instance of the value of a second element with the same name which is in the XML file
reader = XmlReader.Create("c:\\test.xml");
      while (reader.Read())
      {
          reader.ReadToFollowing("chapter");
          Console.WriteLine(reader.ReadInnerXml());
      }
      reader.Close();

I thought that even though it might be an awkward way to do it, the example that doesn't work is walking through each node and then reading to the next chapter element. So why would this only get the first value but not eventually the second, even if in a non efficient manner? Seems like it has something to do with cursor position but I don't know exactly what.

How I see it is that it goes to the first node, and then goes to the chapter element and gets the value, and then the Read method would read the next node after the first chapter element that readtofollowing("chapter") took the cursor to, and then go to the second chapter element following the node that it is currently on, and then walk through any other nodes remaining and fail on an attempt of readtofollowing("chapter") because there would be no more chapter elements left.

So I am missing something very fundamental and important.
