The IDLffXMLDOMNode::GetFirstChild function method creates an instance of one of the IDLffXMLDOMNode subclasses and returns an object reference to that object, which refers to the first child of the calling node in the DOM tree. The type of the object corresponds to the type of the first child node.
Result = Obj->[IDLffXMLDOMNode::]GetFirstChild()
Returns an object reference to the new IDLffXMLDOMNode subclass object if there is a child in the DOM tree. If there are no children, a null object reference is returned.
