   This method retrieves a node specified by ordinal index. Nodes are  
numbered in tree order (depth-first traversal order).
   index of type unsigned long - The index of the node to be fetched. The  
index origin is 0.
Return Value
   Node - The Node at the corresponding position upon success. A value of  
null is returned if the index is out of range.

This is the best thing to do, from my multiple experiences with ecmascript.
