Python 正则表达式匹配多个 headers 及其在多行字符串中的段落

Python Regex to match multiple headers and their paragraphs in multi line string

我正在尝试在 Python 中创建一个 Regular-Expression,它应该在 multi-line 字符串中捕获 header 和对应的文本。示例字符串:

.Main Header
This is the main paragraph in the text. Also this is another sentence.
.Sub-Header
This is secondary header and text.
.Last Header
And this is the last header in the text.

此处 .Main Header.Sub-Header.Last Header 是段落的 header 和接下来的几行 (text until next ".Header" string) 是文本的body。所以我的预期输出是:

Header1 - .Main Header, Text1 - This is the main paragraph in the text. Also this is another sentence.
Header2 - .Sub-Header, Text2 - This is secondary header and text.
Header3 - .Last Header, Text3 - And this is the last header in the text.

我试图组合一个 regex 来满足这个期望并且它几乎可以工作,我面临的唯一挑战是捕获句子之间 dot(.) 的文本(for ex. Text1), 我的 regex 的停止条件是 newlinedot(.) 因为下一个 header 从 dot(.),所以我正在寻求帮助,以区分常规点和换行点作为我的停止标准。

我当前的正则表达式是:

^(.\w+[^\n]+)\n([^\.]+)

对于 Text1 这捕获:

This is the main paragraph in the text

但应该捕获:

This is the main paragraph in the text. Also this is another sentence.

也许试试下面的正则表达式...

^(.\w+[^\n]+)\n(.*?)\.$

...从第二个匹配行开始抓取所有字符,直到行尾的最后一个点。
