find_element_by_xpath() 使用 Selenium 和 Python 显示语法错误

Question

I tried to connect to Twitter using selnium in python. I could not connect using Name or Xpath. The xpath is copied by clicking Inspect and then copy xpath of the specific element. All the tutorials I found regarding connecting to Twitter are old and irrelevant. I enclose the code here. I have error on @id="layers"

Image of the code:

I would be very happy to help.

Code:

from threading import Thread
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
from selenium.webdriver.support import wait

driver=webdriver.Chrome(executable_path="C:\\Webdrivers\\chromedriver.exe")
driver.get("https://twitter.com/i/flow/login")
search=driver.find_element_by_xpath("//*[@id="layers"]/div[2]/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[5]/label/div/div[2]/div/input")
search.send_keys("orlaharty1@gmail.com")
button=driver.find_element_by_xpath("//*[@id="layers"]/div[2]/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[6]/div")
button.click()

Answer 1

You are using double quotes twice. Instead paste the xpath to single quotes 'xpathblabla' Also add driver.implicity_wait(seconds) so you wont get any erros if your driver is fetching elements that aren't loaded yet

driver.get("https://twitter.com/i/flow/login")

#add this line
driver.implicitly_wait(10)
#                                  single quotes
search=driver.find_element_by_xpath('//*[@id="layers"]/div[2]/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[5]/label/div/div[2]/div/input')
search.send_keys("orlaharty1@gmail.com")
button=driver.find_element_by_xpath('//*[@id="layers"]/div[2]/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[6]/div')
button.click()

Answer 2

While constructing an xpath there are two approaches and you can follow any one of them:

• You need to pass the value of the xpath with in double quotes ie "..." and the value of the attributes in single quotes ie '...' . As an example:

   search=driver.find_element_by_xpath("//*[@attribute_name='attribute_value']") # note the ^double quote & the ^single quote

• You need to pass the value of the xpath with in single quotes ie '...' and the value of the attributes in double quotes ie "..." . As an example:

   search=driver.find_element_by_xpath('//*[@attribute_name="attribute_value"]') # note the ^single quote & the ^double quote

Solution

Following the above two convensions discussed above, your effective lines of code will be:

driver.get("https://twitter.com/i/flow/login")
search=driver.find_element_by_xpath("//*[@id='layers']/div[2]/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[5]/label/div/div[2]/div/input")
search.send_keys("orlaharty1@gmail.com")
button=driver.find_element_by_xpath("//*[@id='layers']/div[2]/div/div/div/div/div/div[2]/div[2]/div/div/div[2]/div[2]/div[1]/div/div[6]/div")
button.click()
