Question

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

以下是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>

我想要检索值为1365的th，但我找不到获取值的方法。我猜我必须使用nextsibling或一些父方法，但我遇到了困难。以下是我尝试过的代码

url = 'http://www.mauritiusturfclub.com/index.php/en/racing/results? 
   meeting='+str(race_played)+'-'+str(2012)+'&view=full'
   source_code = requests.get(url)
   plain_text = source_code.text
   soup = BeautifulSoup(plain_text,'html.parser')
   print('Track '+soup.findAll('th',{'width':'10%'})[3])

我遇到的错误似乎没有用，有人能解释我发生了什么吗？谢谢

		<table class="tblgrey">

			<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>

Answer 1

尝试

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)
