I agree with jaytea.
One thing I don't get is the pattern demonstrated by Froggie. (unless it's a random, trivial example) It'll match anything starting with one or more nonwhite space characters, followed by a capital or lower letter v, or followed by a space. Sorry, but I don't see how this pattern is any of the benefits for the match...
malformed expression aside
perhaps that's what you meant with the expression constructed incorrectly?
<-this, however, will make some sense to me, because it'll make sure it ends with the uppercase of lowercase v, or proceeded by a space. At least it has a purpose.
