Whitespace (including newlines), mixed cases etc.

I'd switch b and c. If elementree is not fast enough, I'd switch to
celementree and if that's not fast enough, I'd try some hand parsing.

As someone who messed with perl for a long time, I can attest to their
power an unmaintainability. I stay away from them unless I really need
them. But yes, people like Larry Wall seem to think in a fundamentally
different way so YMMV.
I tripped over a hole that was sticking up out of the ground.
