Several things wrong with this patch:
First, it does not appear to be notice-clean. With error_reporting set to E_ALL,
notices will be displayed about the use of undefined constants.
Second, it will fail to pick up any <br> containing additional attributes (for
instance, an id or a style attribute) so it is insufficient.
Third, it gratuitously transforms the clear attribute to an inline style. This is
unnecessary for our XHTML 1.0 Transitional target. (If it were necessary, it would
also be necessary to be able to merge it with a specified style attribute if present.)
Consider instead working on Sanitizer.php to have the HTML sanitizer output the
/> automatically on manditorily-closed empty elements.
1. It isn't, I didn't test it for that.
2. No it won't, it was designed for this specific case and you're right, it's
3. This is what currently happens if you type <br clear="both"/>, the wiki will
render <br style="clear: both;" />, however if you type <br clear="all" /> or
<br clear="all"> it will output what you gave it.
4. Sanitizer.php is probably better, any suggestions as to where to start?
