推荐答案

您没有解释您是自己编写语法还是从某个地方获取语法。

也许你已经看过这里了。



GitHub - antlr / grammars-v4 ：为ANTLR v4编写的语法;期望语法没有行动。 [ ^ ]

你可以在语法列表中找到 xpath 。



你不要解释你得到了什么样的问题，或者究竟是什么让你陷入困境，因此是一般的答案。

You don't explain if you have written the grammar yourself or got them from somewhere.
Maybe you have looked here already.

GitHub - antlr/grammars-v4: Grammars written for ANTLR v4; expectation that the grammars are free of actions.[^]
You can find xpath in the list of grammars.

You don't explain what kind of problem you get or exactly what gets you stuck, hence the generic answer.
