regex - What is the best way to check URL change with Selenium in Python?

Question

So, what's I want to do is to run a function on a specific webpage (which is a match with my regex).

Right now I'm checking it every second and it works, but I'm sure that there is a better way (as it's flooding that website with getting requests).

while flag:
    time.sleep(1)
    print(driver.current_url)
    if driver.current_url == "mydesiredURL_by_Regex":
        time.sleep(1)
        myfunction()

I was thinking to do that somehow with WebDriverWait but not really sure how.

Answer 1

I was thinking to do that somehow with WebDriverWait

Exactly. First of all, see if the built-in Expected Conditions may solve that:

• title_is
• title_contains

Sample usage:

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

wait = WebDriverWait(driver, 10)
wait.until(EC.title_is("title"))
wait.until(EC.title_contains("part of title"))

If not, you can always create a custom Expected Condition to wait for url to match a desired regular expression.
