I've seen similar codes used in macros, which prompts the question: Does PH support the use of regular expressions (regex) in macros?

I was too, until recently! VB Script supports it, so adding it to the macro language is not essential.
A regular expression (regex or regexp for short) is a special text string for describing a search pattern. You can think of regular expressions as wildcards on steroids.
Here is a good reference.

Tony,
I checked out your reference for regex. Pretty neat. The closest that PowerHome has is the "match" function. Im not at my regular PC so I don't have access to the help file to see how well it is documented. From memory though, it seems to be pretty close to regex.
Let me know your thoughts,
Dave.

Wow, that looks darn close! Too bad it doesn't return the position in the string.

Yeah, I figured that would probably be the weak point. I guess the regex's return the position?
I read through the regex quickstart and it looks like the match function is pretty close all the way down to the metacharacters. But just returning true or false wouldnt be as powerful as position.
Dave.

This is supported in vb script, so no biggie.
