Can we do that one more time, please, but in English?With my IT consultant hat on, It's called "regular expressions". Most modern wordprocessors support them in some sort of advanced mode on search/replace, and they allow incredibly sophisticated processing, combined with the readability and intuitive simplicity of quantum theory mathematics. Fortunately, whenever I'm trying to do that sort of thing, a bit of googling for how to replace X with Y except when there's a Z in the month usually finds a whole slew of answers that someone else has figured out and probably spent hours of screaming frustration knocking the kinks out of.
I do get what you're saying, but I haven't managed to use it -- yet!
And @Astro Pen, I must have missed that post, or I'd have given it a big thumbs-up. If it turns out that I did give a thumbs-up, then I'm pleading old-age memory loss...
