selenium基础用法

from selenium import webdriver
from lxml import etree
from time import sleep
#实例化一个浏览器对象(传入浏览器的驱动程序)
bro = webdriver.Chrome(executable_path='./chromedriver')

#让浏览器发起一个指定的url对应的请求
bro.get('http://125.35.6.84:81/xk/')

#page_source获取浏览器当前页面的页面源码数据
page_text = bro.page_source

#解析企业名称
tree = etree.HTML(page_text)
li_list = tree.xpath('//ul[@id="gzlist"]/li')
for li in li_list:
    name = li.xpath('./dl/@title')[0]
    print(name)

sleep(5)
bro.quit()
