[antlr-interest] Re: antlr as rtf parser?

[lgcraymer]

I wrote one a few years back in PCCTS (actually a subset parser for extracting information from a specification document).  Microsoft 
keeps an up-to-date spec including grammar--look up "RTF" with their search engine.  You'll want a lexer rule to identify keywords 
(anything that looks like   '/' (A..Z | a..z)+ (0-9)* ), keep them in a symbol table with the numbers of arguments for each symbol (I had 
a separate specification grammar to distinguish between keywords with one or two arguments), and use semantic predicates to deal 
with keyword-dependent alternatives.

So, yes it can be done with ANTLR.  I relied heavily on semantic predicate hoisting, so there may be a bit more pain with ANTLR 2.
