Here is a start of a DOM like HTML formater I wrote while working on themes. I hope someone will improve this when I return to the themes stuff... --NirSoffer
I started the WikiDomFormatter, which is already in tla (MoinMoin/formatter/dom_xml.py). It is intended as prototype for solving the problems we have with the generation of valid XML/HTML. I don't think it makes sense to start another such project. IMHO it also makes no sense to reimplement a DOM-like datastructure if we can use DOM insted -- FlorianFesti 2004-01-28 15:18:51
