[antlr-interest] getting data from a grammar

[Brian Nelson]

So I have been working on this for about a week, and I even bought the 
ANTLR book, but I can't seem to find how to get what seems like simple 
data out of the grammar.

Here's a very, very limited example. I am merely trying to get data out 
of CSS files. I guess the questions I have are:
1) Should I be using an AST? I assumes I would, since CSS can br broken 
down to a tree very simply, but upon further reading, it may not 
actually be beneficial since I am not trying to solve a really complex 
language issue...
2) How would one, in speudo code, get the actual data out of the following:

The input would be "aa, bb, cc" and I simply want a list of 
['aa','bb','cc']. I am not trying to process it, just get the list out 
of it, ignoring the commas, in a variable I can use.

    prog : rone (COMMA rone)*
           ;

    rone : IDENT;

    IDENT: 'a'..'z' ('a'..'z')*;
    COMMA: ',';

Thanks in advance,
    Brian
