[python] Webdriver search for webpage tags in selenium

webdriver can search based on tag attributes, ID, name and other elements, and complete some simple operations

In many tutorials and books, there are find_element_by_name, find_element_by_id and other functions to find tags, but in the newer version, these functions no longer exist, and only find_element() can be used

There is no by_XX in the input prompt

There are two main parameters in find_element(), by and value

What attributes are used to search and what is the basis for the search

from selenium import webdriver
import time
import random

driver=webdriver.Chrome()
driver.get('http://www.baidu.com')
#driver.maximize_window()
#最大化浏览器窗口

in_put=driver.find_element(by='id',value='kw')
in_put.send_keys('python')



time.sleep(random.uniform(2,3))

driver.close()
#关闭当前网页
driver.quit()
#关闭所有网页并退出

In the by parameter, class is no longer supported 

 

According to my current experience, currently find_element() only supports id and xpath (expression location tags) as the by parameter, and an error "invalid locator" will be reported in other cases
