you are not too far away, I guess. Instead of using one PARSE, you could
define your own PARSE-TAG function etc.
But, I take this as an opportunity to promote my way ;-). If you take a
look at http://www.fm.vslib.cz/~ladislav/rebol/parseen.r and try:
rsp-section: [
do-block [
use [rsp-tag-name] [
rsp-begin: [...]
rsp-end: [...]
[rsp-begin any [rsp-end (print ["finished section" rsp-tag-name]) break | rsp-section
| rsp-html]]
]
]
]
you may find out, that it works
