Is it possible use regex in virtual tags?

[hiccup]

It could sometimes be useful to be able to use regex in virtual tags.
There are some (but extremely few) references on the wiki and the forum that there should already be some support for it, but I can't find any useful info about it.
It looks like it might be limited to only check if a regex 'is true'? But I also can't find out how that would work.

Does anybody have some more info on this, or perhaps can give some links to more info and/or examples?

this has been requested several times, try to find these topics on wishlist board or (if no luck) create new one. i'll give +1.

I believe only $IsMatch currently supports regex.  It would definitely be useful in a replace function, too.

Thanks for the feedback guys.

I created a new wishlist request for it, since I couldn't find a similar specific earlier wish for it.

B.t.w., I also got the impression (from the wiki) that some $IsMatch regex related feature would be already be possible, but I wasn't able to find any proof or real-world example for that?
