I am trying to get data from a password protected website with Selenium. However I get stuck right in the beginning at login with the following error message:

NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[name="username"]"}
  (Session info: chrome=87.0.4280.66)

The name I use is correct for sure, I inspected the website. Including waiting time did not help either...

My code is:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from getpass import getpass



driver = webdriver.Chrome()


driver.get("https://clearing.apcs.at/emwebapcsem/startApp.do")

print(driver.title)
print(driver.current_url)


# create an object for searchbox
username=driver.find_element_by_name("username")
password=driver.find_element_by_name("password")
# typte the input
username.send_keys("XXXXXX")
password.send_keys("XXXXXX")
driver.find_element_by_name('login').click()

Any suggestions would be appreciated.

To send a character sequence to the Benutzer and Passwort field as the elements are within an <frame> so you have to:

  • Induce WebDriverWait for the desired frame to be available and switch to it.

  • Induce WebDriverWait for the desired element to be clickable.

  • You can use either of the following Locator Strategies:

    • Using CSS_SELECTOR:

      driver.get('https://clearing.apcs.at/emwebapcsem/startApp.do')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"frame[title='menu']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.loginContentBoxInput[name='username']"))).send_keys("Endre")
driver.find_element_by_css_selector("input.loginContentBoxInput[name='password']").send_keys("Endre")

    • Using XPATH:

      driver.get('https://clearing.apcs.at/emwebapcsem/startApp.do')
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//frame[@title='menu']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='loginContentBoxInput' and @name='username']"))).send_keys("Endre")
driver.find_element_by_xpath("//input[@class='loginContentBoxInput' and @name='password']").send_keys("Endre")

  • Note : You have to add the following imports :

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