It would be interesting to know *why* you want to do this.

Is it just for the comfort and convenience of the human reader (an
acceptable reason, though I fear you will be disappointed), or is it because
you are sending the XML to a software application that requires the
attributes to be in a particular order (an unacceptable reason)?
