Well, you could try pxdom:
A special feature of this DOM implementation is that it will maintain a
fixed order of attributes, so you can rely on the output being in the order

Is it always one way or always the other, or a mix?
pxdom will use the short form where possible, unless you ask it to do
canonicalisation (using the DOM Level 3 'canonical-form' parameter).
Unfortunately if you did canonicalisation, the attribute order would be
changed. I might add a separate option as a non-standard extension to turn
off short-forms in 1.0 if anyone else would find it useful - alteratively,
hack line 4193 in version 0.9.
If you need to output short forms in some cases but not in others, that's a
bit more work. What you could do to fool the serialiser is put a Text node
of an empty string inside every element that you want to be output in the
longer form, eg.:
Just don't normalise it before you serialise or the empty text nodes will
Actually, it looks like this trick works in minidom, too.
