Answer 1

如果您只需要该alt值，那么您最好获取img标签而不是div标签。也不需要使用正则表达式来提取alt值

from bs4 import BeautifulSoup

import re

soup=BeautifulSoup("""<div class="couponTable">

<div id="tgCou1" class="tgCoupon couponRow"><span class="spBtnMinus"></span><!-- react-text: 67 -->Wednesday Matches<!-- /react-text --></div>

<div class="cflag"><img src="/ContentServer/jcbw/images/flag_JLC.gif?CV=L302R1g" alt="Japanese League Cup" title="Japanese League Cup" class="cfJLC"></div>

<div class="cflag"><img src="/ContentServer/jcbw/images/flag_JLC.gif?CV=L302R1g" alt="Japanese League Cup" title="Japanese League Cup" class="cfJLC"></div>

</div></div></div>""",'html.parser')

lines=soup.find_all('img')

for line in lines:

    print(line['alt'])

输出
