One possibility is to use Antlr. It is a parser generator tool that
created a recursive descent parser from your grammar.
After a little practice the output (parser) it is quite understandable as well.

There are other tools that do this as also.

I know of a number of LL(1) grammar parser generator tools that do this
but I don't know of any LR(1) grammar parser generator tools that do.
