[drools-user] Using While in drools

[Eliane]

Hello,
i'm trying to do the following with drools
Suppose we have an arrayList in our drl File and we want to compare each 
element in the list to a certain value if they 're equal then do something

for each (element in List) 
  if (element == value)
           doSomething()
  else
         next();

how can i utilize the while logic with drools?
