Looking for pattern matchers

[James Barr]

Hi,

can anyone point me towards a regular expression matcher
that acts like lex in that you can add a number of different
expressions so that a token is returned on matching a
particular expression. I could do it simply by calling
re_exec or the like sequentially for each expression,
but this is a bit inefficient.  I'd like to be able to
add and remove expressions dynamically.

Cheers,
james
