<class 'bs4.element.Tag'>
我们可以利用soup加标签名轻松地获取这些标签内容，这些对象的类型是bs4.element.Tag。但是注意，它查找的是在所有内容中的第一个符合要求的标签。如果需要查询所有的标签，后面会进行介绍。
对于Tag，它有两个重要的属性，就是name和attrs
#!/usr/bin/python3
# -*- coding:utf-8 -*-
__author__ = 'mayi'

# 创建 Beautiful Soup 对象，指定lxml解析器
soup = BeautifulSoup(html, "lxml")
# soup对象比较特殊，它的name为[document]
print(soup.name)
# 对于其他内部标签，输出的值便为标签本身的名称
print(soup.head.name)
# 打印p标签的所有属性，其类型是一个字典
print(soup.p.attrs)
# 打印p标签的class属性
print(soup.p['class'])
# 还可以利用get方法获取属性，传入属性的名称，与上面的方法等价
print(soup.p.get('class'))
print(soup.p)
# 修改属性
soup.p['class'] = "newClass"
print(soup.p)
# 删除属性
del soup.p['class']
print(soup.p)

2.NavigableString
既然我们已经得到了标签的内容，那么问题来了，我们想要获取标签内部的文字怎么办呢？很简单，用.string即可，例如：
#!/usr/bin/python3
# -*- coding:utf-8 -*-
__author__ = 'mayi'
from bs4 import BeautifulSoup
html = """
<html><head><title>The Dormouse's story</title></head>
<body>
<p class="title" name="dromouse"><b>The Dormouse's story&
