Hello, thank you for your answers.
Actually I cannot declare my layers in the XML file because before to create the tile I don't know if I will need one or two shapes for the data source. (e.g. if I render a tile on a border of 2 or 3 shape files) I had already thought to the SQL solution but it would need many other changes so I keep it as a B plan. So I guess that using only <Style> and <Rules> with unsorted shape files I cannot ensure that my roads will be drawn in the right order.
