I have used html5lib in my project. It runs great except a minor
possible error.
I got the following error message:
File "myfolder\parser.py", line 30, in parser
minidom_document = parser.parse(fp)
File "build\bdist.win32\egg\html5lib\html5parser.py", line 144, in

readChunk
IndexError: string index out of range
I think it is because the following code:
if (self._lastChunkEndsWithCR and data[0] == "\n"):
data = data[1:]
self._lastChunkEndsWithCR = data[-1] == "\r"
if the data only contains a single "\n" and self._lastChunkEndsWithCR
happens to be True, then data would be "" after the first two lines.
So data[-1] would then raise an exception.
I have added the following code after the second line and the bug
vanished:
if not data:
return
