一、使用BeautifulSoup解析,能够得到一个 BeautifulSoup 的对象,并能按照标准的缩进格式的结构输出:
from bs4 import BeautifulSoup
soup = BeautifulSoup(html_doc)

print(soup.prettify())
#

# <br># The Dormouse's story<br>#

# The Dormouse's story
#
#

# Once upon a time there were three little sisters; and their names were
#
# Elsie
#
# ,
#
# Lacie
#
# and
#
# Tillie
#
# ; and they lived at the bottom of a well.
#

# ...

二、简介：
Beautiful Soup 是一个可以从HTML或XML文件中提取数据的Python库.它能够通过喜欢的转换器实现惯用的文档导航,查找,修改文档的方式.Beautiful Soup会节省数小时甚至数天的工作时间.

f = urllib2.urlopen(url)
req = f.read()

soup = BeautifulSoup(req)
content = soup.findAll(attrs={"name":"readonlycounter2"})
subId = content[0].string.split(',')[1]
subName = soup.html.body.h1.span.string

content = soup.findAll(attrs={"class":"subdes_td"})
subType = content[0].string
subLeg = content[1].string

content = soup.findAll(attrs={"colspan":"3"})
subTime = content[2].string
subFile = content[7].div.string

应该可以满足你的需求

怎么使用beautifulsoup获取指定div标签内容，例如
html="""

....

i like it

----------------------------
然后代码（大概）
from bs4 import BeautifulSoup
soup = BeautifulSoup(html);
content=soup.html.body.div ?? #这怎么用存在的class属性直接指定到该div下。
