I didn't say it is never useful, just rarely useful.

No, I think you can do this without being able to look into sosofos. You
can use the (data (current-node)) procedure to get the text of nodes.
You can also set up a rule that checks every character as someone else
mentioned recently. Finally, DSSSL proper has an optional "regex"
feature that would allow you to do these kinds search and replaces. I
don't know when or if Jade will support it because DSSSL is a large
standard and there are many interesting parts to implement (plus there
is XSL).

I would suggest that the simplest thing for you to do is use Python,
Perl or Awk on the output of Jade. There is no reason to contort your
stylesheets horribly rather than using a "filter" post-process.
