I don't know quite what you mean by "recursive parsers" but I'd
suggest you look at parsing techniques developed in functional
languages. Here's a starting point:


http://www.cs.uu.nl/wiki/Swierstra/PublicationsByYear


in particular this paper:


http://www.cs.uu.nl/people/doaitse/Papers/1996/DetErrCorrComPars.pdf


IIRC Swierstra has extended these techniques to deal with left
recursion but I do not have a reference for that.


(there is a "... in Java" paper there if you prefer something more
imperative.)


cheers
Peter.
