Pretty arrogant, if you don't even know OP's problem, much
less the OP himself? Perhaps the language he is dealing with
is a regular language, in which case regex is... just what
the doctor ordered? Perhaps the OP has a proof for that?
What do you know?
Regex is a sharp tool. Much more Perl's variant, which is
a tad beyond regex. You gotta learn what it's good for and
what ain't. Like a good cook's knife. You might cut off your
toe with it, but if you want to dig a trench in your back
yard, you better use something else.
BTW, you can build fine parsers with Perl regex. It just makes
for the first stage (lexer) (and a bit, see above), but it
works a charm.
