我在尝试从中生成代码时收到以下错误：

是否有任何修复此 ANTLR V4 语法的建议？
您的错误消息的最后一行非常有说服力。如果你看一下语法，每个单词都是大写的。这意味着这只是词法分析器规则，并且有错误。解析器规则完全不存在。在花时间阅读此文件之前，请联系此语法的发布者或搜索解析器规则。
我认为 JoeyACC 的工作结论在这里 - https://gist.github.com/JoeyAcc/375663dfc21cd7ec4d35ea8f7ff251d0#file-xquery31-g4
另一种方法是采用此 Antlrv4 XQuery 1.0 语法并添加 3.1 的缺失部分：https://github.com/bluezio/xquery-parser
我最终为 XQuery 3.1 创建了自己的 Antlr4 语法。它位于：https://github.com/xqdoc/xqdoc/tree/master/src/main/antlr4/org/xqdoc
