Funny you should ask that. There's that popular templating framework that is really good at transforming a flat or tree-ish structure of arrays and objects into a flat string. Also has a nice textual persistence format which lets you mix XML literals with processing instructions; well supported by most text editors out there. The framework is not all that great for other uses, but really shines at templating. You mix and match botch standard DOM -- including XSLT and whatnot -- and its fast, simple native arrays and objects. Available on many servers. The framework originally targetted Perl, but later on was re-implemented in C as standalone entity, for better performance. They call it `PHP'.
