如何从变量中删除多余的文本？ [Python]

Question

我从一个使用授权的站点制作了一个解析器，最后我得到了一个包含必要信息和 html 垃圾的通用块。如何只留下像

INEEDTHISTEXT

这样的文字？

我现在拥有的：

[<div class="dnevnik-lesson__task">
<i class="dnevnik-lesson-icon"></i>INEEDTHISTEXT
 
 
 
            </div>, <div class="dnevnik-lesson__task">
<i class="dnevnik-lesson-icon"></i>INEEDTHISTEXT
 
 
 
            </div>, <div class="dnevnik-lesson__task">
<i class="dnevnik-lesson-icon"></i>INEEDTHISTEXT
 
 
 
            </div>, <div class="dnevnik-lesson__task">
<i class="dnevnik-lesson-icon"></i>INEEDTHISTEXT
 
 
 
            </div>, <div class="dnevnik-lesson__task">

            </div>, <div class="dnevnik-lesson__task">
<i class="dnevnik-lesson-icon"></i>INEEDTHISTEXT
 
 
 
            </div>]

我需要什么：

INEEDTHISTEXT INEEDTHISTEXT

等等

我尝试了replace()，[cut:]，但没有成功。

您应该使用 HTML 解析器，例如 Beautiful Soup，但这里有一个简单的正则表达式，应该适用于这种情况。它可能不适用于所有网页：

import re

html = """[<div class="dnevnik-lesson__task">
<i class="dnevnik-lesson-icon"></i>INEEDTHISTEXT
...
"""

print(re.findall(r">([\w]+)\s+<", html))

这将打印

['INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT',
 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT',
 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT',
 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT',
 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT',
 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT',
 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT',
 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT', 'INEEDTHISTEXT']
