Also edited numerious tests that were expecting wrong output - they now expect
correct output. Note that a few **still fail** because the output before moving
to ELementTree wasn't correct either. So I set the expected output to what I
think it should be so we don't forget about it later.

I should also note that the 'safe-mode' tests are failing. However, I believe
the current expected output is correct as it is valid html. Interestingly,
these tests passed prior to this fix. We'll need to special case safe-mode here.
