I would recommend the PCCTS tool set. PCCTS stands for the
Pe Compiler Compiler Tool Set. It contains, among other things,
a parser generator. This parser generates generates an arbitrary look
ahead recursive decent parser. This parser, can parse any LR(k)
language not just LR(1).

PCCTS is free and you can download it from the web. The source
is included. Hope this helps.
