how to click the login button using selenium xpath

Question

I am trying to login to a website using python so that I can get some of their text from the website.

Here is my code. There always an error at the end of the code after the id and password code.

import os
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.by import By

driver = webdriver.Chrome(executable_path=r"C:\chromedriver\chromedriver.exe")

driver.get('https://www.saramin.co.kr/zf_user/auth')

driver.implicitly_wait(3)

driver.find_element_by_name('id').send_keys('<<my_id>>')
driver.find_element_by_name('password').send_keys('<<my_password>>')

driver.find_element_by_xpath('//*[@id="frmNIDLogin"]/fieldset/input').click()

HTML source of the button:

The html doesn't match the xpath in your code. And post the html as text please, not as an image. — Guy

Eventually I figured it out! Thanks for your answer though.

Here is the final code.

driver = webdriver.Chrome(executable_path="C:\chromedriver\chromedriver.exe")

browser = webdriver.Chrome('C:\chromedriver\chromedriver.exe')

driver.get('https://www.saramin.co.kr/zf_user/auth')

driver.implicitly_wait(3)

driver.find_element_by_name('id').send_keys('ID') driver.find_element_by_name('password').send_keys('PW')

driver.find_element_by_xpath( '//*[@class="btn-login"]' ).click()

It worth noticing '//*[@class="btn-login"]' match two elements. It works because the relevant element is first in the DOM hierarchy, it might not always be that way.

The xpath is incorrect, it doesn't match anything in the page. Try

driver.find_element_by_xpath('//form[@id="login_frm"]//button[@class="btn-login"]').click()

or simply use submit() function on the <form>

form = driver.find_element_by_id('login_frm')
form.submit()

In the first case you were using 'id' ('//*[@id="frmNIDLogin"]) for click button, because 'id' changes every time page loads it was giving error. But in the second case when you used class ( '//*[@class="btn-login"]' ) it worked because it remains same every time page is loaded. Also as mentioned above the value of id in first case was wrong.
