Yes, it is madness, and yes, unfortunately, it has been done. There's
that language called XSLT which you may remember... Frankly, I find
S-Expressions far easier to read than XML, so much so that I actually
wrote a small utility once upon a time to convert S-expression input
into XML output (and I did it mainly to make XSLT programs I once
wrote when I was experimenting with it easier to read! I don't have
the code anymore, but I remember that it wasn't difficult to do with
Ruby). There's also this little project:

http://weitz.de/cl-who/

that generates HTML/XML from Common Lisp.
