I have a program that saves/loads to/from XML. I have a main class
Building, and a subclass House(Building). When I save the code I instruct
each object to save itself to XML (using ElementTree), so House adds
itself to the XML tree.<br>
My problem is when I load the XML. Before having subclasses what I did
was to send the XML object (again in ElementTree) to the object and let
itself load. Now, with subclasses, if I send the House XML to Building I
get a Building instance, when I need a House instance.</blockquote><br>

Are you referring to a Python object? If so you may assign a class to the
object's __class__ attribute.<br>
class A:pass<br>
class B:pass<br>
b = b()<br>
print b.__class__ # displays <class __main__.B at 0x011BB9C0><br>
b.__class__ = A<br>
print b.__class__ # displays <class __main__.A at
