如何找到与美丽的汤特定的文本标签？ [英] How to find tag with particular text with Beautiful Soup?

问题描述

我有以下的HTML（标记为\\ n换行符）：

I have the following html (line breaks marked with \n):

...
<tr>
  <td class="pos">\n
      "Some text:"\n
      <br>\n
      <strong>some value</strong>\n
  </td>
</tr>
<tr>
  <td class="pos">\n
      "Fixed text:"\n
      <br>\n
      <strong>text I am looking for</strong>\n
  </td>
</tr>
<tr>
  <td class="pos">\n
      "Some other text:"\n
      <br>\n
      <strong>some other value</strong>\n
  </td>
</tr>
...

则返回刚才的固定文本：

推荐答案

您可以通过一个常规的前pression到的findAll 的文本参数，如下所示：

You can pass a regular expression to the text parameter of findAll, like so:

import BeautifulSoup
import re

columns = soup.findAll('td', text = re.compile('your regex here'), attrs = {'class' : 'pos'})
