Why don't you just negate the condition of matching.
I mean

When (Not matched) Then // ... your code

Alternatively, you can go here[^] too.

thanks Rajeev - negating the condition of matching, is breaking one of the policies, thus had requested for the same.
i had tried [^] also - it doesnt work with the pattern i had submitted above.
