Note that the object oriented model already provides a feature that allows you to treat data "generically" or "specifically". Subtyping (or interface inheritance)! So what we really need is "tree node" base class or interface. That's also the answer to Simon's question about what should replace the DOM as a generalized interface for trees. All we need is a simple "tree node" interface. The grove model supports that. In fact I would argue that that is probably the most important thing that the grove model DOES support. The DOM "node class" also supports this. If you use that class along with NodeList and NamedNodeMap and ignore the rest of the DOM then you can get all of the benefit that you are going to get out of the DOM API as an abstraction. There is no need to dumb down your data to elements and attributes. Just use nodes. -- Paul Prescod - ISOGEN Consulting Engineer speaking for only himself http://itrc.uwaterloo.ca/~papresco "Remember, Ginger Rogers did everything that Fred Astaire did, but she did it backwards and in high heels." --Faith Whittlesey xml-dev: A list for W3C XML Developers.
