I'm working on a 3d engine system.
I need to save/load data in the systems objects to/from XML files.
When I say objects, I mean C++ objects. (These generally correspond to
scene objects, but that consideration isn't important as far as
loading/saving goes.)

I think I have a reasonable grasp of XML, it's method of data
representation, and parsing XML files. 
(At the moment I'm looking at using the expat XML parser for it's
callback based system, so I don't have to load/parse the whole -
potentially v large - XML file into memory before I create objects).

The problem I'm having is deciding how to get the data from the XML
parser into the C++ objects. 
How is this normally done?
Do you pass the completed/parsed XML node to the C++ object creator?
Do you create the object object and set it's members with data from
the completed/parsed XML node?

What's the best/most flexible way to do this, or are what are pros and
cons of various methods?
Pointers to some examples would be greatly appreciated.

Thanks

Jim Williams
