In the process of making this site, I needed a facility to strip attributes from HTML elements. My first stop was on the
strip_tags page in the PHP manual. However, the function on there were pretty poor and borked out a lot. Google didn't provide any better results, so I ended up having to make one. The result are pretty good. After a few tweaks I ran over 10,000 tests on different web pages and didn't have any problems.
