Try treetop: http://treetop.rubyforge.org/
It is not very fast (not for megabytes of text), but it's very simple to
use. I also wrote an article with some examples and recipes for avoiding
typical errors: http://whitequark.org/blog/2011/09/08/treetop-typical-errors/

Also, there is racc (ruby's yacc) and antlr-ruby, but these are somewhat more
arcane.
