I think we already had this discussion two years ago in the context of XML decoding ;): http://mail.python.org/pipermail/python-dev/2007-November/075138.html > And how would > you reuse it if it was a codec?

I have implemented an XML codec (as part of XIST: http://pypi.python.org/pypi/ll-xist), that can do that: >>> from ll import xml_codec >>> import codecs >>> c = codecs.getincrementaldecoder("xml")() >>> c.encoding >>> c.decode("<?xml") u'' >>> c.encoding >>> c.decode(" version='1.0'") u'' >>> c.encoding >>> c.decode(" encoding='iso-8859-1'?>") u"<?xml version='1.0' encoding='iso-8859-1'?>" >>> c.encoding 'iso-8859-1' Servus, Walter _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
