I don't see how what you do after each "pull" would be any different
than what you have to do within each call from SAX. You still have to
build a state machine with a pull-model API, but now your state machine
can simply take the form of procedural refinement:

reader.Read();
if (reader.LocalName == "foo")
{
   // I know I'm in the foo element here
   reader.Read();
   if (reader.LocalName == "bar")
   {
      // I know inside of foo/bar here
      ...
   }
}
