[New-bugs-announce] [issue13987] Handling of broken markup in HTMLParser on 2.7

[Ezio Melotti]

New submission from Ezio Melotti <ezio.melotti at gmail.com>:

The attached patch fixes a few problems with HTMLParser on 2.7.
Instead of raising error when invalid markup is detected, the parser now consumes the invalid input and proceeds.  This patch is a partial backport of #1486713.

After this two more patches will follow.
The first will get rid of errors raised while parsing declarations and should also solve #13576:
     def unknown_decl(self, data):
-        self.error("unknown declaration: %r" % (data,))
+        pass

The second will take care of "bogus comments" (see #13960).

Once this is done HTMLParser should be able to parse (almost) everything.  I'm planning to commit this before the release of 2.7.3.
