Re^2: Using a regex to extract a version from a Un*x path

I hadn't thought it through trying to split on '/'. Interesting. I'll have to see where that goes. Thanks.

Such an amazing bunch of replies. Thanks so much, all answers are very much appreciated.

I, too, very much like JavaFan's approach of Re: Using a regex to extract a version from a Unx path. However, since I've already composed this reply, you might as well see it. To avoid the confusion introduced by the presence of `'V2'` in some paths, I depend on the presence of the magical `'V2DepCheck'` sub-string. (JavaFan neatly avoids this issue by parsing right-to-left, but the regex approach I use must parse left-to-right.) Many more regexes are defined than in other approaches, but I find that it sometimes pays to be painfully explicit* when the problem set is ill-defined and mutable, and maintenance may be an issue.
