Scott and Steve, This is strange, I just looked in my Perl docs; Perl /does/ support look behind: (?<=...) zero width positive look behind (?<!...) zero width negative look behind
I wonder why CF doesn't support this? Maybe because it's totally possible to do it other ways (positive look ahead could be the same as positive look behind, depending on where you put your pattern in the regex). However, if you are used to using look behind, and it's not in CF, that's a let down. I wonder if there are any cases where look behind is absolutely necessary...or is it just a different syntax in CF? Any experts out there know the answer?
