What i'd like to do is take a variable created via trigger:
QuestMob = A blue cat

What i'd like to do is strip off the common words in the variable, ie A/the etc.
I was thinking something like %replace(@questmob,a, "") but the problem is if 'a' is in multiple locations.. like in the above example.

Any idea how to just strip the words.. I could even create a stringlist of the words..

Use %subregex instead.

QuestMob=%subregex(@QuestMob,"(?:a|the|of)\b","")

Of course, you can add on to the string list within the (?:) bit. You will need to add capital versions of it as well, though (A|The|etc).

The following pattern should take care of the case sensitivity:

"(?i)(?:a|the|of)\b"

Though I have the feeling that %subregex defaults to case-insensitive.

So in Charneus' example it would appear as this:

Perfect!
Would it be easier to keep the string within the trigger or create a seperate stringlist?

I'd probably keep the string within the trigger.

By the way, make one small change... I had it this way before, but I guess I accidentally removed it...

Questmob = %subregex(@Questmob, "\b(?i)(?:a|the|of)\b","")

Otherwise, you'd wind up stripping things like "Car[b]the[\b] is sitting here."

Glad we could help, and thanks, Anaristos - I wasn't sure if CMUD did accept (?i) for insensitivity.
