My Mercury XML parser has a very similar interface, and is quite fast
(since it does not use higher order combinators - lesson here)

(see also ftp://ftp.dcs.shef.ac.uk/home/tomas/xml.ps)

No need to port the SWI prolog parser IMHO - somebody just need to
write documentation for mine. I'd do it if I had the time.
