在h1标头之前找到一个表

Question

I want to find the table in a HTML using the h1 just before using BeautifulSoup

 <a name="playerlist"></a> <div class="navbuttons"> <a href="#toc" class="linkbutton">up</a><a class="linkbutton" href="#players">next</a> </div> <h1>Participants</h1> <table class="main"> <thead> <tr> <th>Name </th><th>Major</th><th>Class of</th><th>Ranking</th></tr> </thead> <tbody> <tr> <td>Mike Finge</td><td>Applied Maths</td><td>2015</td><td>155</td> </tr> </tbody> </table> 

In the example above I would like to find the table just under h1 ? How can I do this with BeautifulSoup? Thanks in advance

Answer 1

我认为您应该在BeautifulSoup中使用h1+table ，因为表格位于h1下方

Answer 2

Since the table element is the sibling of the h1 you can do this, ie, you can use the ~ operator available for the select method.

>>> HTML = '''\
... <a name="playerlist"></a>
... <div class="navbuttons">
... <a href="#toc" class="linkbutton">up</a><a class="linkbutton" href="#players">next</a>
... </div>
... <h1>Participants</h1>
... <table class="main">
... <thead>
... <tr>
... <th>Name </th><th>Major</th><th>Class of</th><th>Ranking</th></tr>
... </thead>
... <tbody>
... <tr>
... <td>Mike Finge</td><td>Applied Maths</td><td>2015</td><td>155</td>
... </tr>
... </tbody>
... </table>
... '''
>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(HTML, 'lxml')
>>> soup.select('h1 ~ table')
[<table class="main">
<thead>
<tr>
<th>Name </th><th>Major</th><th>Class of</th><th>Ranking</th></tr>
</thead>
<tbody>
<tr>
<td>Mike Finge</td><td>Applied Maths</td><td>2015</td><td>155</td>
</tr>
</tbody>
</table>]
