Re^3: Help with regular expression

[graff]

toolic's solution is the right answer for the few examples you gave, but since you haven't said anything about the larger context of strings you might be getting as input, how should the following be treated by your intended regex?

(foo 12)
foo 12 bar
foo 12, bar 34
Foour score and 12 years ago there were 34 bars in this town.

All the above would fail, given toolic's very tight use of anchors (^ and $). If that's what you want, then the problem is solved.
