TypeError with html5parser.tostring()

[Drew Smathers]

System info:

Python : (2, 6, 1, 'final', 0)
lxml.etree : (2, 3, 0, 0)
libxml used : (2, 7, 3)
libxml compiled : (2, 7, 3)
libxslt used : (1, 1, 24)
libxslt compiled : (1, 1, 24)

Operating System: Mac OS X 10.6.7

With this example given in documentation:

  from lxml.html import tostring, html5parser
  tostring(html5parser.fromstring("<table><td>foo"))

I get the following error:

html5 parsing seems to be completely broken because of this bug

[Jimmy Yuen Ho Wong (wyuenho)]

Just did some digging and it seems the html5lib 0.9 has a treebuilder module called etree_lxml.py. Replacing the entire content of lxml/html/_html5builder.py with just this line to delegate the names seems to have fixed this bug:

from html5lib.treebuilders.etree_lxml import *

Fixed in lxml 2.3.1.
