最近爬取一个报表的数据，里面有个INPUT元素，没有ID,NAME,CLASS是重复使用的。没有办法，只好学习by_xpath的详细用法；
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
#浏览器启动配置
browser = webdriver.Firefox()
browser.maximize_window() # 最大化浏览器窗口
url= "file:///D:/py/ftn/a.html"
browser.get(url)
qssj =browser.find_element_by_xpath('//div[@widgetname="STARTDATE"]/div/input')
qssj.send_keys('2020-02-24')
下面是我构造的a.html的文件

格式调不好，具体可以复制到本地，建一个HTML文件仔细看；
其中， widgetname是这个HTML的自制标签；
个人理解，就是从当前页面中查找以”widgetname="STARTDATE"开头的元素，然后在找后面的DIV中的第一个input元素；
本想做个笔记自己看，发现解理的不深刻，还是将参考的语法发上来备记
