Did I already recommend this? Sorry if that's a duplication.
One more example of SXML together with SRFI 110 sweet expressions
(indent sensitive LISP syntax). Those two blend well together. I'm
using them embedded in XML (XSLT) here:

(Be sure to view this as source, not in the browser!)
Remarks: a) this is served from Chicken b) it's a rather simple but
complete payment system, docs coming up here:
http://ball.askemos.org/A0cd6168e9408c9c095f700d7c6ec3224/?_v=search&_id=1856&_go=2
Wilma, Fred and Bamm-Bamm are each running the script above.

Dear Yves, with SXML you could write transformation rules as Peter has
shown in www.more-magic.net/docs/scheme/sxslt.pdf
<http://www.more-magic.net/docs/scheme/sxslt.pdf>.
I'm not experienced with SXML, but AFAIK they would generate a similar
effect as the procedures in your example below.
Best wishes,
