如何使用ANTLR 4转义括号字符

LPAREN: '(';
RPAREN: ')';

import org.antlr.v4.runtime.*;
import org.antlr.v4.runtime.tree.*;

public class Main {
    public static void main(String[] args) throws Exception {
        // 创建输入流
        ANTLRInputStream input = new ANTLRInputStream("(Hello World)");

        // 创建词法分析器
        MyGrammarLexer lexer = new MyGrammarLexer(input);

        // 创建词法记号流
        CommonTokenStream tokens = new CommonTokenStream(lexer);

        // 创建语法分析器
        MyGrammarParser parser = new MyGrammarParser(tokens);

        // 设置错误监听器
        parser.removeErrorListeners();
        parser.addErrorListener(new DiagnosticErrorListener());

        // 解析输入文本
        ParseTree tree = parser.startRule();

        // 创建自定义的监听器或访问者
        MyListener listener = new MyListener();

        // 遍历解析树
        ParseTreeWalker walker = new ParseTreeWalker();
        walker.walk(listener, tree);
    }
}

class MyListener extends MyGrammarBaseListener {
    @Override
    public void enterParentheses(MyGrammarParser.ParenthesesContext ctx) {
        String text = ctx.getText();
        // 处理括号字符的转义逻辑
        String escapedText = text.replace("(", "\\(").replace(")", "\\)");
        System.out.println("Escaped text: " + escapedText);
    }
}
