See http://msdn.microsoft.com/en-us/library/windows/desktop/ms756022(v=vs.85).aspx for an explanation. What you need to do is get the first child of the memberNumber node, and then use get_nodeValue() on that node. Basically, to obtain the text inside the node you obtain the child of that node that is of type NODE_TEXT.
