I think this principle of always using the simplest regex that does the job

cases, there's a good chance someone in a year's time is going to come back
to it and need to change it. Complex regexes are intrinsically very hard to
debug, so it's a good idea to avoid them if you can.
Then, a corollary of this argument would certainly be that the
simplest available
*technique* is a very good one. substring-before/after comes to my mind even
though this splits on the first occurrence. A fn:string-split would be
nice to have,
but it's easy to implement.
