首先我们导入模块

# 前提是安装了lxml以后，指定解析器
html = BeautifulSoup(html,'lxml')
# 输出格式化以后的dom文档 # print(html.prettify())
#获取第一个标签 print(html.find('html',recursive=False))
#获取标题信息 print(html.title)
# 标签名称 print(html.title.name) #获取标签的文本 print(html.title.string)
# 获取单个属性
print(html.p['id'])
#获取所有属性 print(html.p.attrs)#获取标签下所有文本
print(html.p.get)#这个连标签一起获得
print(html.p.get_text())#获取的纯文本
#fand 查找 name:b标签名 res = html.find(name = 'p',attrs={'name':'p1','id':'p1'})
#同过id查找 res = html.find(id="p1") print(res)#查找所有符合条件的标签
res = html.find_all(name=['a','b'])
