Here's a possible start:
:0
* ^From: Errol Casey
* B ?? TODAY:[ ]*\>[ ]*\/High\>.*Low.*
{
:0 fhw
| formail -I "Subject: $MATCH"
:0:
$TESTDIR/ztestmbox # $TESTDIR is *my* variable
}
Running your message through this filter delivered it exactly as sent
(headers and body), except:
$ diff testmsg ztestmbox
48d47
< Subject: How to parse and resent info embeeded in an email
77a77
Subject: High 88F; Low 72F. Humid; breezy later.
Obviously, the first From: condition would need to be changed to
something suitable. This serves two purposes -- lessen the risk of
filtering the wrong messages, and preempt unnecessary body searches in
the next condition. And the final action needs to be whatever suits
your needs. If you're intending to strip or otherwise munge the body,
or want to include the string "TODAY:", or want tomorrow's weather, etc.
there's more work left as an exercise.
[While doing this, Matt already got back with one. I offer this anyway
because it's pure procmail.]
