There are plenty of XML template languages, for instance Genshi (for Python; http://genshi.edgewall.org/ http://genshi.edgewall.org/ ), which is kind of an extension to XSL. However, compared to text-only template engines, they are typically much slower. If you want to master the complexity problem arising in large templating projects, you might want to consider logicless template languages instead, which are at the other end of the scala -- lightweight and fast.
