This is a regression from 3.2:
Traceback (most recent call last):
File "/home/antoine/3sted/twisted/lore/test/test_lore.py", line 542, in test_setTitle
secondTitle.setAttribute('class', 'title')
File "/home/antoine/opt/lib/python3.3/xml/dom/minidom.py", line 743, in setAttribute
attr.ownerDocument = self.ownerDocument
builtins.AttributeError: ownerDocument

Trivial reproducer:
>>> e = minidom.Element("span")
>>> e.setAttribute("class", "version")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/antoine/cpython/default/Lib/xml/dom/minidom.py", line 743, in setAttribute
attr.ownerDocument = self.ownerDocument
AttributeError: ownerDocument

That's invalid usage. You are supposed to create new element nodes through the document's createElement method. "unattached" nodes are not supported. |

Then Twisted will have to change. From http://docs.python.org/library/xml.dom.minidom.html "Applications should not instantiate the classes themselves; they should use the creator functions available on the Document object." If they insist on not using createElement, they use internal API, and need to adjust that to new Python versions. Closing as invalid. |
