I would have to disagree. There are things that regex just can't at a
fundamental level grok. Things like nested brackets (e.g. the standard
blocking syntax of C, javascript, php, etc.). It's not a parser, and
despite all the little lookahead/behind tricks that enhanced regex can
do, it can't at a fundamental level _interret_ the text it sees. This
task involves interpreting what the text you're looking for actually
means, and should therefore be handled by something that can
interpret.
Also, (I haven't tested it, but) I don't think that example you gave
would work. Without any sort of quoting around the "http://";
, I would assume the JS interpreter would take that double slash as a
comment starter. Do tell me if I'm wrong, though.
