what could i do? there are other buttons on the page with the same class etc, the only variables are

"Answer1","Answer2"

Answer 1

To click on the link with text as Vote you can use either of the following solutions:

• css_selector :

   driver.find_element_by_css_selector("a.button.expanded.vote[onclick*='Answer1'][onclick*='Answer2']").click()

• xpath :

   driver.find_element_by_xpath("//a[@class='button expanded vote' and contains(.,'Vote')][contains(@onclick,'Answer1') and contains(@onclick,'Answer2')]").click()

---

Update

Induce WebDriverWait for the desired element to be clickable as follows:

• css_selector :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.button.expanded.vote[onclick*='Answer1'][onclick*='Answer2']"))).click()

• xpath :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='button expanded vote' and contains(.,'Vote')][contains(@onclick,'Answer1') and contains(@onclick,'Answer2')]"))).click()

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
