Josh,
For what it's worth, \w will match '_' (it's true of REs pretty much
everywhere, and I just tried and as3 is the same). I played around with
your example a bit, but I can't offer any more insight. The closest I
got would leave stray '.'s on the ends of the matches, and you'd have to
clean those up manually anyway. I need to learn lookahead...
Alternately, you could String.split('.') and validate the individual
tokens.

Date: Fri, 3 Oct 2008 17:52:42 +1000
I need to do two things:
1: make sure the string matches /^[a-zA-Z0-9_]+(?:\.[a-zA-Z0-9_]+)+$/
2: extract all the individual words (not the dots)
I Can't use \w because it doesn't match "_".
At the moment I'm just using String.split(".") after using the regexp to
test validity.

Hmm, maybe I am not understanding your needs.
My pattern works on your example of
"*&%*&^objectA()*&)(*&908objectB,objectC"
The resulting array contains:
objectA
908objectB
objectC
Which is what I thought you wanted.
Also, the problem in your RE *is* the non-capturing group which
is
consuming your 'objectB.' You can verify this by using a
lookahead
assertion (?=) instead of the noncapture (?:) group.
var patt:RegExp = /([a-zA-Z0-9_]+)(?=\.?(?:[a-zA-Z0-9_]*))/g;
This pattern results in the same output as my simple pattern
using
lookahead assertions.
If these aren't the results you were looking for let me know and
I can
take another look.
