[antlr-interest] How to read input from a file?

I want to read a series for strings from a file and parse them.  My program only parses the first line in the input file though.  How can I have it parse the whole file?
 
My input file contents:
 
'Hello''ORACLE.dbs''Jackie''s raincoat''09-MAR-98'
 
I'm trying to read all strings that begin and end with a quote (').  So, my output should consist of the following:
Hello
ORACLE.dbs
Jackie's raincoat
09-MAR-98
 
INSTEAD, I only get the following:
Hello
 
My Main file looks like the following:
 
import java.io.*;
class Main {    public static void main(String[] args) {        try {            L lexer = new L(new FileInputStream("input2.inp"));            P parser = new P(lexer);            parser.setFilename("input2.inp");            parser.startRule();        } catch(Exception e) {            System.err.println("exception: "+e);        }    }
 
My .g file looks like:
 
class P extends Parser;
startRule
 : n:DEFAULT_QUOTE        {System.out.println("Matched default quote with: "+n.getText());}    ;
class L extends Lexer;
options { k=2;}
// one-or-more letters followed by a newlineDEFAULT_QUOTE:   ( '\''!                    (~('\'') )+                    '\''! )    ;
protectedLINETERMINATOR    :   '\r' '\n'   // DOS    |   '\n'        // UNIX    ;    WHITESPACE : LINETERMINATOR  |  ' ' | '\t' | '\f' ;}
 
Any help will be greatly appreciated.  Thank you.
