How well does LuaExpat work if HTML is not clean or valid?
My experience with expat (NOT used with LuaExpat) is that it makes a
valiant effort to deal with a few things. But for the most part, invalid
HTML generates an error and aborts. I think there is a way to get expat
to continue if there is a validity error. For instance, I think you can
get it to handle the case where a an EndElement has the wrong name. But
for the most part invalid HTML, like invalid C, is hard to fix and make
any sense of. And I don't know how easy it would be to get LuaExpat to
be tolerant of errors.
My general rule is "always use valid HTML" :-)
