<td>My home address</td> 例:
s = '<td>My home address</td>'

请改用下一个
>>> s = '<table border="0" cellspacing="2" width="800"><tr><td colspan="2"><b>Name: </b>Hello world</td></tr><tr>'
>>> soup = BeautifulSoup(s)
>>> hello = soup.find(text='Name: ')
>>> hello.next

使用下面的代码使用 python beautifulSoup 从 html 标签中提取文本和内容
s = '<td>Example information</td>' # your raw html
soup = BeautifulSoup(s) #parse html with BeautifulSoup
td = soup.find('td') #tag of interest <td>Example information</td>
td.text #Example information # clean text from html
