    </table>

    </div>

    </div>  
    </body>
    </html>

但是我只想获取<span style="font-weight:bold">标记内的所有内容。有最佳的方法吗？就我所知，我只能使用.split来实现它，但我认为这不是一种非常优雅或非常理想的实现方式。我想了解实现它的最佳方法或最优雅的方法。

这是我想要的输出：

[
N,
FACTURA,
femenino,
singular,
.
.
.]

Answer 1

You can use regular expressions here:

import re
result = re.findall(r'<span style="font-weight:bold">(.*?)<', html_document)

提取关键部分的字符串，其中内容用<span style =“ font-weight：bold”>标记括起来
