Re: [rules-users] string replace collision problem
I am sorry, but that would not work either. The first rule would not catch
those sentences that have both S and SF in them.
You will have to work in three steps and use an intermediate value.
1. Change SF to Q
2. Change S to VOL
3. Change Q to S
Separate your steps by using ruleflow or agenda-groups. Make sure to update
your WM after every change.
Sorry for the confusion.

Frank

Hi,
Sorry, but I fogot about you :-(.
It does not work because both wolfgang and I did get your question wrong.
If I were you, I would try to work from the opposite direction and check
whether a String matches S but not SF. Than replace that S by VOL.
A second rule could than safely check for SF and replace that by S.
In short, reverse your salience, check that S is not SF and make sure that
you replace the right S in the RHS of your rules. You do not want to
update the WM.

Frank
