You have no chance unless you implement your own serializer because of
many reasons, one being that attribute order isn't significant - the
order in which they get written out is allowed to be different each
time (others include the namespace prefix problem you've come across,
entites and character references eg &apos; versus ', & #160; versus '
' etc).

XML canonicalization is a big topic and has its very own w3c rec:

Could you not compare in memory structures and do the work in whatever
tool is comparing the XML?  That way serialization issues aren't
