如BeautifulSoup文档中所述
您可以使用：
soup = BeautifulSoup(html)results = soup.findAll("td", {"valign" : "top"})编辑：
要返回仅具有valign =“ top”属性的标签，可以检查tag
attrs属性的长度：
from BeautifulSoup import BeautifulSouphtml = '<td valign="top">.....</td> <td width="580" valign="top">.......</td> <td>.....</td>'soup = BeautifulSoup(html)results = soup.findAll("td", {"valign" : "top"})for result in results : if len(result.attrs) == 1 : print result返回：
<td valign="top">.....</td>
