I have this regular expression:

I want it to extract all ABs from the string but it gives this:

How do I get it to work? Will regular expressions do the trick in this case at all?
Most likely I just fail to understand the concept of regular expressions but I’ve tried several patterns and none of them have worked so far.

find() stop at the first match and returns the start index:

var i = 0

while r.find("ab aa bb, ab, ab", i) >= 0:

	i = r.get_capture_start(1) + r.get_capture(1).length() 	
    prints(r.get_capture(1),  r.get_capture_start(1))

gives:

#ab 0
#ab 10
#ab 14
