Python Selenium Webdriver - Try except loop

Question

I\'m trying to automate processes on a webpage that loads frame by frame. I\'m trying to set up a try-except loop which executes only after an element is confirmed

Answer 1

The answer on your specific question is:

from selenium.common.exceptions import NoSuchElementException

link = None
while not link:
    try:
        link = driver.find_element_by_xpath(linkAddress)
    except NoSuchElementException:
        time.sleep(2)

However, there is a better way to wait until element appears on a page: waits

Answer 2

Another way could be.

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

try:
    element = WebDriverWait(driver, 2).until(
            EC.presence_of_element_located((By.XPATH, linkAddress))
    )
except TimeoutException as ex:
            print ex.message

Inside the WebDriverWait call, put the driver variable and seconds to wait.
