#2225 enhancement closed fixed (fixed)

microdom shouldn't bork on malformed tags when beExtremelyLenient is enabled

Reported by: Jonathan Lange Owned by:

Cc: Branch:


When microdom encounters things like <div al!\n ign="center">, it should ignore the whole tag if beExtremelyLenient is enabled.

Justification: Firefox, Safari and IE all ignore malformed tags, and the purpose of beExtremelyLenient is to let us get a handle on bad HTML.

I basically like this.

I'd rather not have whitespace mashing in files which aren't otherwise modified (I don't see any semantic changes in, and the tests pass if I revert it), but this has to happen some time, so now that I've gone to the trouble of looking at it let's go ahead and merge it.

The only problem I have is that I don't think the string "True" has any particular semantics in this case. In some cases, XHTML requires a string like "on" or "checked"; in others it accepts any value (including the empty string).

If "True" is random here, I'd suggest replacing it with the empty string, then merge. Otherwise go ahead and merge as-is.

Guh. Trac really freaked out Firefox somehow and messed up a bunch of attributes as part of that review. Puttin gthem back...

[16:32]  <jml> glyph: so, sux uses "True" as the default value for an attribute.
[16:33]  <jml> glyph: you want me to change that (totally untested) behaviour?
[16:33]  <glyph> jml: Nope
[16:33]  <glyph> jml: that's a good enough reason to leave as-is
[16:33]  <glyph> jml: perhaps we should revisit it later
[16:33]  <jml> sure

#2227 is the revisit-it-later ticket.

(In [18633]) Make sux even more lenient when beExtremelyLenient is enabled.

Don't explode when we find weird characters and line breaks in HTML. Instead, muddle on as best we can. This behaviour inspired by the way Firefox handles really bad HTML.
