去年的工作，发第一篇试试

 # coding= utf-8
import requests
from lxml import etree  # path = './web/new_index.html'
fp = open('E:\\0爬虫监控平台\\错误码视图\\应用监控平台.html','rb')
html = fp.read().decode('utf-8')   #.decode('gbk')
print(html) 
selector = etree.HTML(html)   #etree.HTML(源码) 识别为可被xpath解析的对象
print(selector)
infos = selector.xpath('//*[@id="tabs"]/ul/li[3]/a/text()') 
print(type(infos)) #运行结果 
print(len(infos))  #运行结果 11
print(infos)
