I don't know. It looks like it would be the first child of the subnode
you're working at. I'm not sure if that first child can be a nil
pointer, so you need to check yourself or someone else has to answer
this question.
But it is easy to jump to the implementation of FindNode() yourself:
1. Put the cursor on the function call to <yourxmldoc>.FindNode()
2. klick the right mouse key
3. in the popped up menu select "Find Declaration of FindNode"
4. hit the keys Shift+down (arrow)
After Step 3 you're shown the class declaration, then after the fourth
step the cursor is sitting in the implementation of the method in
question. Then you can read the code.
Have fun,
Marc
