Reading is not the same as writing.
What happens if I want a different format for writing the data out, for
instance? Maybe I want everything in one line. Or maybe I want it
indented by 3 spaces instead of 1 tab.
The output from simplexml is as it is - it's simple (which is why it is
so named). If you want it to output in a different format, you need to
format do it yourself.
