How will the REGEX_REPLACE() function work?

Agree, this is the simple solution. Did you already have a library picked
out? Are there any requirements to license and language? Would it be useful
if you could limit the amount of memory the library can use?

What I would really like to do, is rewrite the thing! However, I do not
have an unlimited amount of time for this project. I'll look into Henry
Spencers old library and let you know what I decide to do.
