The main difference between a generated parser based on algorithms and hand crafted regex is when the parser blows up it says: "Syntax error at character #34 expecting BLAH, FOO, and BAR symbols." Regexen do this: "Hi, oh thanks, I *love* hacks like this. You crafted this shellcode really well so that it looks mildly like a payload. Super awesome I'll just pass this vaguely HTTP string right on to our app." :-) -- Zed A.
