使用beautifulsoup检索信息

Question

我是beautifulsoup的新手，我想检索标签中的特定元素，但问题是没有办法识别标签

下面是html元素

<div class="tbl_racing_head" > <table class="tblgrey"> <thead> <tr> <th width="65%" class="aln_left"><a name="1"></a>Race 1. THE ZILLAH CUP.<span class="pull-right"><a href="/index.php/en/racing/results?view=full#top" id="back-top">Back to Top</a></span></th> <th width="10%">1365 m</th> <th width="15%">Rating 25-0</th> <th width="10%">12h45</th> </tr> </thead> </table> </div>

Answer 1

试试看

s = """<div class="tbl_racing_head" >
        <table class="tblgrey">
            <thead>
            <tr>
              <th width="65%" class="aln_left"><a name="1"></a>Race 1. THE ZILLAH CUP.<span class="pull-right"><a href="/index.php/en/racing/results?view=full#top" id="back-top">Back to Top</a></span></th>
              <th width="10%">1365 m</th>
              <th width="15%">Rating 25-0</th>
              <th width="10%">12h45</th>
            </tr>
            </thead>
        </table>
        </div>"""
from bs4 import BeautifulSoup
soup = BeautifulSoup(s,'html.parser')
for tr in soup.findAll("tr"):
    print(tr.find("th", {'width':'10%'}).text)
