# <b>The Dormouse's story</b>
soup.a
# <a class="sister" href="http://example.com/elsie" id="link1">Elsie</a>
如果想要得到所有的<a>标签,或是通过名字得到比一个tag更多的内容的时候,就需要用到Searching the tree中描述的方法,比如: find_all()
soup.find_all('a')
# [<a class="sister" href="http://example.com/elsie" id="link1">Elsie</a>,
# <a class="sister" href="http://example.com/lacie" id="link2">Lacie</a>,
# <a class="sister" href="http://example.com/tillie" id="link3">Tillie</a>]
