Question

I am trying to capture an Error which would restart my program and change proxy but I am unable to catch the error as its stored like this and classes are dynamically named :

so I am trying to catch the xpath by this function but I am un able to do so.

def has_error(browser):
        try:            #/*[contains(text(), 'technology')]/html/body/span/section/main/div/article/div/div[1]/div/form/p"
            browser.find_element_by_xpath("/html/body//*[contains(text(),'technology')]")
            return False
        except: return True
        if not has_error(browser):
            print('Error found! , aborted!')
            browser.quit()
            os.execv(sys.executable, ['python'] + sys.argv)

Answer 1

To Handle dynamic element use WebDriverwait and following Xpath Startegy.

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


element=WebDriverWait(driver,30).until(expected_conditions.element_to_be_clickable((By.XPATH,'//p[contains(.,"technology")]')))
print(element.text)

You can check if the source of the web-page contains special text.

if 'By signing up, you agree to our ' in browser.page_source:
    pass
    # TODO Exception
