from lxml import objectify from lxml import etree

print etree.LXML_VERSION, etree.LIBXML_VERSION (2, 2, 2, 0) (2, 6, 32)

class test (objectify.ObjectifiedElement) : ... pass ... good = objectify.Element ("abc") print type (good), repr (good) <type 'lxml.objectify.ObjectifiedElement'> <Element abc at 7f0797587fc8>

bad = test ("abc") Segmentation fault

I read that you have to instantiate a parser with objectify.makeparser and use the method makeelement from there. However I would expect that at least not Segmentation Fault happens, if someone is using the normal inheritance as used to be. regards Daniel
