Some upstreams are dead and some packages using PyXML will never be ported by upstreams to use something else than PyXML (e.g. lxml). $ python2.7 Python 2.7.1+ (2.7:572fbd9ca28f+, May 16 2011, 21:40:05) [GCC 4.5.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import xml, _xmlplus >>> xml_modules = set(xml.__all__) >>> _xmlplus_modules = set(_xmlplus.__all__) >>> xml_modules - _xmlplus_modules set(['etree']) >>> _xmlplus_modules - xml_modules set(['xpath', 'utils', 'schema', 'marshal', 'xslt']) >>> -- Arfrever Frehtes Taifersar Arahesis
