I'm doing a natural language parser and here is a part of the code that I've written: class MyParser extends Parser; options { k = 3; } sentence : subject predicate ; subject : pronoun | noun ; pronoun : "I" | "you" | "he" | "she" | "him" | "her" | "they" | "them" { System.out.println( "pronoun matched" );} ; noun : "apple" | "banana" | "cherry" { System.out.println( "noun matched" );} ; class TagJapLexer extends Lexer; options { k = 3; filter = true; }    More>>


I'm doing a natural language parser and here is a part of the code that I've written:


			
class MyParser extends Parser;

options { k = 3; }

sentence : subject predicate
;

subject : pronoun | noun
;

pronoun : "I" | "you" | "he" | "she" | "him" | "her" |
"they" | "them"
{ System.out.println( "pronoun matched" );}
;

noun : "apple" | "banana" | "cherry"
{ System.out.println( "noun matched" );}
;

class TagJapLexer extends Lexer;

options { k = 3; filter = true; }

ALPHA : ( 'a'..'z' | 'A'..'Z' | '-' )+
{ System.out.println( "Word: " + getText() ); }
;


My problem is I don't know how to get the text from the parser for each matching rule, because I would like it to be displayed like this:



noun found: apple
pronoun found: I

I've tried using { System.out.println( "pronoun matched" + getText());} but it still didn't work. Can anybody help me solve this problem. Thanks!
