[issue17802] html.HTMLParser raises UnboundLocalError:

[Thomas Barlow]

Thomas Barlow added the comment:

Just adding a patch here with a few unit tests to demonstrate the issue, comments here are welcome.  This is my first patch, I believe I have put the tests in the correct place.

It appears the problem only occurs if there is an incomplete XML entity where a sequence of valid characters (for an XML entity's name) lead to the end-of-file.

The test case for "a&b " passes, as it detects the space as an illegal character for the entity name.
