Answer 1

You can use XmlSerializer and create a simple class with properties according to the template:

public class User
{
   public UserId{get;set;}

   ...
}

And serialize the class to XML file.

There's a good example here.

Option #2:
If for some reason you do not want to use XmlSerializer use XmlWriter - in order to prevent forgetting to close elements I suggest you use "AutoClose" XmlWriter - I've blogged about how to create this simple class on my blog - XmlWriter that automatically close elements using IDisposable
