问BeautifulSoup获得标签描述信息python源码怎么写

上代码：

#! /usr/bin/env python
# -*- coding: utf-8 -*-

tag_content = """
<dd
    isStop = "1" class='isStop'
    matchcode="201409066001"
    matchnumcn ="周六001"
    starttime = "1409994000000"
    endtime ="1409993820000"
    isattention = "0"
    hostname="北九州" guestname="福冈黄蜂"
    leagueid = "533"
    hostteamid = "46148"
    visitteamid = "12193"
    matchid="1000817"
    leagueName="J2联赛"
    class="league_533"
    style="display: none;"
    ishot="0">
pass</dd>
"""
from bs4 import BeautifulSoup
tag_soup = BeautifulSoup(tag_content)
style_str = tag_soup.dd["style"]
print style_str.split(":")[1].lstrip()[:-1]

Beautiful Soup不能直接获得“none”，不过我们能容易地得到display: none;，然后用python很容易处理了。

用tag attrs["style"] 然后正则

1.如果python的cgi中能有专门获取html中style或者属性的方法最好，这style 既没有id name 也不是value。不知道能不能get出来
2，我的超级笨办法我的思路：把这一大块用'''包裹，之后，另开一个py文件，用open打开刚才的要检索的大块，用readlins（）去读取那大块中的每一行，用正则匹配出 style=“dispaly：”，之后再用str的切片 切出来。

s = """  <dd

from pyquery import PyQuery
p = PyQuery(s)

a=p("dd")
print a.attr('style')
print a.attr('hostname')

display: none;
北九州
