Nice but I did want to bust all the date values out to separate elements of the @res array. Your non capturing braces though give me the clue I think to fix it properly, but I still can't quite get it: 

@res = $_ =~/(\d{4}-\d\d-\d\d).*dates processed: ((:?\d{4}-\d\d-\d\d,?
+ ?)*)/
# still captures last result twice
# input
# 2009-02-02 06:12:57,500 dates processed: 2009-01-31, 2009-01-29, 200
+9-01-30
# output
# 2009-02-02, 2009-01-31, 2009-01-29, 2009-01-30, 2009-01-30

Update

Oeps, I am not splitting them with the above either, fooled myself because my debug testing printed the list out with a join ", ", doh!

Cheers,
