Answer 2

Without the HTML it is not clear about the number of white spaces between Sélectionner Taille: and 19. So discounting all the white spaces to invoke click() on the element with respect to the variable using Selenium and python you need to to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies:

• Using variable in XPATH:

  size = '19'
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[starts-with(@title, 'Sélectionner Taille') and contains(@title, '" +size+ "')]"))).click()
  

• Using %s in XPATH:

  size = '19'
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[starts-with(@title, 'Sélectionner Taille') and contains(@title, '%s')]"% str(size)))).click()
  

• Using format() in XPATH:

  size = '19'
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[starts-with(@title, 'Sélectionner Taille') and contains(@title, '{}')]".format(str(size))))).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
