The reason why ``chameleon.genshi`` depends on lxml is "match-templates", which do require a post-render step where the document must be parsed with XPath-selector methods (bound to particular elements in fact) passed on to callbacks. It's a bit convoluted. While I do think the concept of match templates is cool, perhaps it should be let gently out of the package again, because as it happens, the support isn't very solid. Genshi is a great language in itself; I don't think it needs match templates to qualify. > The non-lxml versions of chameleon.core rely on the "etree" module, which is > only present in Python 2.5+.

Let me note two things: 1) ElementTree is only used to validate inserted content in debug-mode. 2) On Python 2.4, the ``ElementTree`` package is added as an "install_requires" dependency. \malthe _______________________________________________ Repoze-dev mailing list Repoze-dev@lists.repoze.org http://lists.repoze.org/listinfo/repoze-dev
