Dear, I have a thread that route (upoc tclproc) the HL7 messages depending of the “sending facility” from the MSH segment.
I have one route for AAA, a second route for BBB but for the remaining trxId I want to send them to a generate route with hcitpsmsgkill.
I try the _HCI_static_route_ but the messages for AAA and BBB are sent too to this route detail (and the others too), great but I would like to do it more cleanly (no wasting cpu time to kill the AAA and BBB messages)
I just want to route the messages that aren’t from AAA and BBB to be send to this route
I try the following pattern routes without any success:
Code:!AAA|!BBB
[^AAA]|[^BBB]
.[^AAA]|[^BBB]
.[^AAA]|[BBB] + wild card on
but I got “No routes defined…”Need help, thx
Yves

If there are no cases where the routing will start with the text that is being excluded you could use:
(?!AAA|BBB).*
This particular expression excludes routing starting with AAA or BBB, but will allow anything else.
ie it will exclude
AAA
BBB
AAADDDD
BBBAAA
but will include
BAAA
ABBB
DDD
for info anything inside of (?!REGEX) not equal to REGEX.
.* will allow match the rest of the text.

Elisha:
Be careful with look-ahead either positive or, in this case, negative. It can be very slow. Also when use the | symbol you must ambiguosly define what you mean. The expession you have: (?!AAA|BBB).* would mean do a negative look ahead for a string starting with AA followed by A or B followed by BB.
It would be better defined as (?!(AAA)|(BBB)).* which would say do a negative look ahead for a string that starts with AAA or BBB
