Zope's implementation can be used freestanding AFAIK. There's also SimpleTal that is totally independant from Zope. > My problem is that I want to write as little Python code as possible to make > the templates (almost) stand alone and thus readable without the backend code. > I can transform the XML language to a more usable XML format beforehand, no > problem, but I then need to access the result from the template - and that's > almost impossible without XPath. > > Does anyone have an idea what I could use? Any hints are helpful. Perhaps a TAL + elementTree combo could do ? (first parse the source XML with elementTree, then pass the resulting tree as the context of the ZPT/SimpleTal template) My 2 cents -- bruno desthuilliers python -c "print '@'.join(['.'.join([w[::-1] for w in p.split('.')]) for p in '[EMAIL PROTECTED]'.split('@')])" -- http://mail.python.org/mailman/listinfo/python-list
