使用regex和re在括号之间获取文本

I have an array of strings that I want to extract specific content from:

我有一个字符串数组，我想从中提取特定的内容:

['link.description', 'button.text]] </li>']

I want to get the following output:

我想得到如下输出:

link.description
button.text

For each string in the array, I do the following:

对于数组中的每个字符串，我执行以下操作:

str = re.findall('(.*?)\]+', str)

With the above regex, I can only get button.text. How would I get both link.description and button.text? I tried using:

使用上面的regex，我只能获得button.text。如何同时获得link.description和button.text?我试着使用:

str = re.findall('(.*?)\]*', str)

But the above just gives me a bunch of blanks in the return str.

但上面只是给了我返回str中的一些空格。

You don't need regex for a simple task like this. Besides, your code will probably make more sense without regex.

像这样的简单任务不需要regex。此外，如果没有regex，您的代码可能会更有意义。

In this case, you can simply use str.split():

在这种情况下，只需使用string .split():

>>> thingies = ['link.description', 'button.text]] </li>']
>>> different_thingies = [thingy.split(']')[0] for thingy in thingies]
>>> different_thingies
['link.description', 'button.text']

Hm, try \]+. Is that what you want? (Asterisk says "match zero times or more" which -as you can see- matches really often.)

嗯,试试\]+。这是你想要的吗?(Asterisk表示“匹配零次或更多”，你可以看到，这种匹配非常频繁。)
