As Rob Marscher pointed out, using the DOM support can be tricky. What
you get out is not always what you put in, even if what you put in was
technically well-formed. Dreamweaver-y code (empty <font></font>
garbage) is a nightmare.

It's also slower than regex (which is slower than strpos()). So yeah,
it's super convenient and clean, but there are big trade-offs to using
it in some cases.
