Re: [Boost-users] regex_search? Which subexpression smatch'ed?

Whatever you could work out would be greatly appreciated. ----- Original Message ----- From: "John Maddock"

It's backtracking that gets you: each time the "lowest sub-expression set" gets updated you'd need to store a complete history of previous settings so you can backtrack out again. However, now I think about that some more, I actually think it might be possible after all :-)
