我正在使用 python 进行文本处理。基本上我想提取两个地标之间的内容。具体内容如下。如何设计正则表达式以获取“查找意图漏洞”和“打印意图摘要”之间的文本。谢谢

你需要使用正则表达式吗？使用 str.find 或 str.index 查找每个标记然后使用切片提取它们之间的内容可能更简单。

但是，使用正则表达式：

re.search(r"(?s)Find intent vulnerabilities\n(.*?)Print intent summary\n", text).group(1)

正则表达式在这里可能有点矫枉过正。为什么不使用索引和切片？

>>> l = len('test123')
>>> s = '  test123 somestuff here test456   '
>>> s.index('test123')
2
>>> s.index('test456')
25
>>> s[2+l:25]
' somestuff here '
