Don't know whether it's what you're after, but check out the GOLD
parser (http://www.devincook.com/goldparser/). The grammars need to
be 'compiled' into tables that can then be loaded and used by the
parser, but they are stored as external files. Unfortunately the
source isn't available, but the file-format specs are. I'm working on
something similar myself, but I've only managed the lexer so far...I
guess I'm just lazy and easily distracted :)
