Python正则表达式匹配多行

问题描述

我正在尝试从 Python 中的网页获取

标记的内容.我使用了以下代码:
matchResult = re.search(r'<ul\s*content="MSL">(.*)</ul>', queryResult, re.MULTILINE)
这不起作用.但是，如果我使用
删除换行符queryResult = queryResult.replace('\r','').replace('\n','')
它有效.

I'm trying to get the contents of a <ul> tag from a webpage in python. I used the following code:
matchResult = re.search(r'<ul\s*content="MSL">(.*)</ul>', queryResult, re.MULTILINE)
This does not work.However if I remove the line breaks by using
queryResult = queryResult.replace('\r','').replace('\n','')
It works.

PHP 中的这个正则表达式在不删除换行符的情况下工作正常:preg_match('@<ul\s*content="MSL">(.*)</ul>@msU', $queryResult, $matches);


This regular expression in PHP works fine without removing line breaks:preg_match('@<ul\s*content="MSL">(.*)</ul>@msU', $queryResult, $matches);


如何使用 Python 匹配多行?

How can I match over multiple lines using Python?

推荐答案

还包括 re.DOTALL 选项，这将允许 . 字符匹配换行符.

Include the re.DOTALL option as well, that will allow the . character to match newlines.
