There are a few options: - Change c-Element's tp_name to "xml.etree.ElementTree.Element". - Register a reduce function for c-Element's that serialises them by constructing an equivalent py-Element and returning the latter's .__dict__ via the third return value: http://docs.python.org/3/library/copyreg#copyreg.pickle - Add an entry mapping "builtins.Element" to "xml.etree.ElementTree.Element" to _compat_pickle.IMPORT_MAPPING (which is used by Lib/pickle.py:_Pickler.find_class()). I haven't tried to implement either of these approaches. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16076> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
