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())
# <html>
# <head>
# <title>
# The Dormouse's story
# </title>
# </head>
# <body>
# <p class="title">
# <b>
# The Dormouse's story
# </b>
# </p>
# <p class="story">
# Once upon a time there were three little sisters; and their names were
# <a class="sister" href="http://example.com/elsie" id="link1">
# Elsie
# </a>
# ,
# <a class="sister" href="http://example.com/lacie" id="link2">
# Lacie
# </a>
# and
# <a class="sister" href="http://example.com/tillie" id="link2">
# Tillie
# </a>
# ; and they lived at the bottom of a well.
# </p>
# <p class="story">
# ...
# </p>
# </body>
# </html>
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.

怎么使用beautifulsoup获取指定div标签内容，例如
html="""
<html>
<body>
<div class="a">....</div>
<div class="b">i like it</div>
</body>
</html>
----------------------------
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。
html="""
<html>
<body>
<div class="a">....</div>
<div class="b">i like it</div>
</body>
</html>
----------------------------
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。
