我正在尝试清理可能有两个连续markdown标题的文本，如下所示：## Foo bar\n\n## Another bar\n\n文本的其余部分还包含其他标题和其他\n\n。
\n\n始终是文字字符，而不是实际的换行符。整个文本是一行。
让我用例子来描述一下：

• 实施例1*

foo bar##Lorem ipsum dolor sit amet, consectetur adipiscing elit.\n\n##Sed faucibus metus eu est sodales, a eleifend neque mollis.\n\nAliquam erat volutpat. Aenean ultrices odio leo, at vulputate enim porttitor non. Nam sodales vitae turpis quis sollicitudin. Mauris molestie eget purus nec scelerisque.\n\n##Sed eu erat quis nulla lobortis dapibus.\n\nPraesent suscipit, ante quis pretium varius, tellus ex consectetur elit, eu pharetra nunc metus cursus ex.\n\n##Aenean eu tempus dolor.\n\n Vivamus scelerisque sit amet mi eget dignissim. Fusce sit amet ligula vel tortor tincidunt porta.\n\n

应匹配：##Lorem ipsum dolor sit amet, consectetur adipiscing elit.\n\n##Sed faucibus metus eu est sodales, a eleifend neque mollis.\n\n
实施例2

foo bar##Lorem ipsum dolor sit amet, consectetur adipiscing elit.\n\n Some text here ##Sed faucibus metus eu est sodales, a eleifend neque mollis.\n\nAliquam erat volutpat. Aenean ultrices odio leo, at vulputate enim porttitor non. Nam sodales vitae turpis quis sollicitudin. Mauris molestie eget purus nec scelerisque.\n\n##Sed eu erat quis nulla lobortis dapibus.\n\nPraesent suscipit, ante quis pretium varius, tellus ex consectetur elit, eu pharetra nunc metus cursus ex.\n\n##Aenean eu tempus dolor.\n\n Vivamus scelerisque sit amet mi eget dignissim. Fusce sit amet ligula vel tortor tincidunt porta.\n\n

应该什么都不匹配。
我尝试过的所有正则表达式都匹配，即。也贪婪地捕获部分段落而不仅仅是标题。有什么想法吗
谢谢你！
