Hi Volker, I appreciate your comments. Basically, the reason why this code generator exists is the fact that I do not want to hard-code the resulting xml in any way. The users of the web/db framework of which this solution is part of might like the "web page" definition I offer them, but, some might want to extend it. While dom allows me to traverse an xml hierarchy - it does not allow me to give "meaning" to the tags. The only way to do that (for me) is to represent the tags as classes with containers containing other classes (tags) and so on. Since I do not know ahead of time what the tags will be - I need to generate the code to actually handle them. Can you suggest a better approach or did you already do that and I just missed it? :) Cheers, Ognen -- http://mail.python.org/mailman/listinfo/python-list
