Well in many browsers for example there is a internal warning and error log
(window). Which yet does not (need to) claim to be a official W3C checker. It
has positive effect on web stabilization.
For example just looking now I see
Ezio Melotti ezio.melo...@gmail.com added the comment:
The strict/tolerant mode mainly works by using either a strict or a tolerant
regex. If the markup is invalid, the strict regex doesn't match and it gives
an error. The tolerant regex will match both valid and invalid markup at the
same

The old patch warned already the majority of real cases - except the missing
white space between attributes.
The tolerant regex will match both:

Note that the regex and the way the parser considers the commas changed in

adding a group for the comma is no longer doable.
In theory, the approach you

It's also in 3.2 and 2.7 (but it's quite recent, so if you didn't pull recently
you might have missed it).

I looked at the new patch http://hg.python.org/lookup/r86952 for Py3 (regarding
the extended tolerance and local backporting to Python2.7):

Ezio Melotti ezio.melo...@gmail.com added the comment:
The HTMLParser is not suitable for validation, even the strict mode allows some
non valid markup (and it might be removed soon).
Also I don't think it's easy to call a self.warnings() without trying the
strict mode first. The tolerant

A note for the curious: I changed the keyword name from 'tolerant' to 'strict'
because the stdlib has other examples of 'strict' as a keyword, but the word
'tolerant' appears nowhere in the documentation and certainly not as a keyword.
R. David Murray rdmur...@bitdance.com added the comment:
I have committed a version of this patch, without the warnings, using the
keyword 'strict=True' as the default, and with a couple added heuristics from
other similar issues, in r86952.

I agree that a tolerant mode would be good (and often requested). String

to a policy.
