Re^2: Regex question

So much of your code can be simplified by changing
while ($str =~ /([A-Z,0-9])/ig) {
to
while ($str =~ /(([A-Z,0-9])\2*)/ig) {

The posted code is beyond not elegant. It's in the realm of needless complexity.

Update: Forgot to mention:

Besides that, I don't know why you imposed a limit on which characters can be processed. The OP didn't mention anything about ignoring characters which are neither unaccented latin alpha, ~~roman~~latin? digits nor a comma. (Did you even mean to put that comma there?)

1. Stuck to the char set provided by OP. (BTW, I think that while the "I," "V," "X," "L," "C," "and "M" fill the bill as "Roman numerals," "0" .. "9" are Arabic.) 2. No. Dumb mistake!	[reply]
