Proposal: do everything in one go

[lig]

It looks like html-sanitizer does a lot of wibbly-wobbly things to produce the result.

It seems possible to implement every html-sanitizer feature using a smart plugin system for a custom SAX parser rules realization.

I'm going to come back here and implement this when I have enough time.

Yes, this should be possible. The core of the cleaner is now more than 8 years old, so I probably would do it differently too these days :-)

Luckily we have a testsuite now to catch regressions. However, it is not very exhaustive yet, so maybe it would also be good to expand the testsuite before moving to big refactorings. (No must-have at all, but would certainly make reviewing eventual pull requests easier!)
