I've asked in another thread, I know it may be next to impossible to parse, and I reckon maemo mapper is very good as it is now, but http://www.viamichelin.com offers more knobs (click on the options link, you have at least "recommended by michelin", "quickest", "shortest", "economical" and "discovery", as well as options for selecting pedestrian/bike route and type of road) and it's usually more accurate in this part of the world.
It has an "export on gps" link, that gives you an xml file, but I think it's next to useless (in my test route it only gives the first and last point coordinates, probably because the viamichelin gps can do the routing by itself).
