Usage of Regular expression for pattern matching is anytime better than
using simple string matching in the sense that
- it gives more power
- it can reduce the number of signatures needed.
Apart from that speed-wise is reg-exp matching still much faster than
simple sring matching like Bayer-moore or similar algos ??
any pointers or references will be great.
thanks a lot
