Hi all. Quick quesiton about PCRE vs. POSIX-extended regular
expressions.
How much of a difference is there between these two types of regular
expressions. I know I've read that PCRE is faster, but is it that much
of a difference?
A while ago I had to write a bunch of regular expression patterns for an
application and I wrote them using the POSIX-extended functions, but now
I'm debating converting them to their PCRE equivalents, because a) it
says they are often faster, and b) I want the experience in both.
Any thoughts on this?
Cheers and TIA,
Pablo
