You need to write a parser. Google will find you many samples and libraries that you can use to help you.

That's way beyond the scope here. Way, way, way beyond the scope. There are entire books on the subject. Searching for "Parser" on Wikipedia may help. Or indeed "Parser" in Google (you evidently didn't try very hard).

But, if you're trying to go from a grammar to random statements, that's more generative use of a grammar. An entirely different subject. Search for "Generative Grammar".

Be prepared to spend a month or so reading ;-)
