我想清理以下页面http://209.105.250.69:8382/以获取使用 Python 的侦听器数量

<td>Current Listeners:</td>
<td class="streamdata">28</td>

这是网站上的代码

>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(s)
>>> td1 = soup.find('td', text='Current Listeners:')
>>> td2 = td1.find_next_sibling('td')
>>> td2.text
'28'

您需要使用像BeautifulSoup这样的 HTML 解析器。我不会发布完整的解决方案（因为看起来你没有尝试做任何事情），但这里有一个演示：

from bs4 import BeautifulSoup as BS
html = the_above
soup = BS(html)
print soup.find_all('tr')

这将打印<tr>代码中的每个标签（作为列表）
