Question

我试图从文本文件中提取一些信息。我能够匹配我需要的，问题是有太多的比赛。

信息在文中重复了几次。重复之间有独特的文本，但我无法弄清楚如何让它在遇到这个文本时停止匹配。在我的前瞻之后放置任何东西似乎打破了正则表达式。

希望有一种方法可以做到这一点，并且失败了，这是一种限制它将获得的匹配量的方法。

以下是我现在所拥有的以及我正在搜索的样本：

                  (?<=anniversary\s|\s<plaintext>).+(?=\s+)



<subpod title=''>
   <plaintext>birth of Gustav Schäfer (1988- ): 25th anniversary

birth of Brad Silberling (1963- ): 50th anniversary

任何帮助表示赞赏

正则表达式，限制匹配数量/停止匹配的东西在这里？
