ANTLR4 解析不适用于重复的文本

Question

我已经成功解析了下面的文件信息，直到第 "To be finalized..." 行具有给定的语法。但是一旦我们在 "To be finalized..." 之后接收到更多数据，解析器就会跳过 1-3 条记录，并在输出中首先给出 header 和最后 2 条记录（4-5）。

问题：如何更改语法，才能解析所有数据？ 非常感谢您 in-light 解决以下问题：

And Record 4 and 5 + details after.

解析器正在跳过记录 1-3，但已读取所有文件。

Answer 1

我认为令牌 "FUNCTION" 消耗了所有记录，在您的情况下您应该使用非贪婪规则，尝试以下操作：

FUNCTION:[\%][\%](.*?)[\%][\%];
