Data scraping using python webdriver

Question

I am trying to click a button using Firefox - python - webdriver

But every time error comes:

selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: .pull-right show-toggle with-icon

Am I missing something here? after login and couple of steps I am reaching on one page where I need to click on the button with below class name.

child = driver.find_element_by_class_name('pull-right show-toggle with-icon')
child.click()

Any other way of doing this ?

Hmm... Actually with your code you should get InvalidSelectorException as search by_class_name doesn't support compound class names... Update your code with original selector. Also check whether your button located inside an iframe — Andersson

Hi Andersson - the button is not under iframe, you can check HTML Page i have added — GAURAV CHHABRA

update your code with original selector, what actually this means? — GAURAV CHHABRA

It means that driver.find_element_by_class_name('pull-right show-toggle with-icon') should trigger InvalidSelectorException, but not NoSuchElementException... Also there is only little HTML sample on provided image. Are you sure that there is no iframe? — Andersson

Infact i tried parent child relationship as well he is able to find class "Hidden Print" but then also for child it says no class name like this, — GAURAV CHHABRA

As per provided piece of HTML, you can click your button with following code:

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

button = wait(driver, 10).until(EC.visibility_of_element_located((By.XPATH,"//a[@data-toggle-text='Hide details']")))
button.click()

amazing thanks alot it worked finally, but will you be able to give me heads up what xpath is doing here

i got it, its interesting

XPath is more flexible than other approaches to locate element. In this particular XPath you check DOM for ancor with specific attribute (data-toggle-text in this case)

this is working fine for me but problem now is this button will sometimes exist or sometimes not, so when i am running my cude it throws timeout exception because the button is not present how can i build this condition that if you didn't find that button then exit the code

i used pass in place of driver.quit() :)
