Loop : if element exist click on it else contenue to the next step on Python-CodePudding

im trying to delete all product from cart. So i search for a loop who : if element exist i click on this element else this element doest more exist. So if not exist i can go to the next step. I write this code but not working :

WebDriverWait(self.driver, 30).until(
             EC.presence_of_all_elements_located((By.XPATH, '//*[@data-testid="RemoveProductBtn_btn"]')))
        if len(self.driver.find_elements_by_xpath('//*[@data-testid="RemoveProductBtn_btn"]')) > 0:
        self.driver.find_element_by_xpath('//*[@data-testid="RemoveProductBtn_btn"]').click()

CodePudding user response：

Why don't you try to handle the exception instead?

try:
   WebDriverWait(self.driver, 30).until(
             EC.presence_of_all_elements_located((By.XPATH, '//*[@data-testid="RemoveProductBtn_btn"]')))
except ElementNotFoundException:
   self.driver.find_element_by_xpath('//*[@data-testid="RemoveProductBtn_btn"]').click()

CodePudding user response：

Use try..except block. it will check if elements present then iterate and click else go except block and then continue.

while True:
    try:
        elements=WebDriverWait(self.driver, 20).until(EC.presence_of_all_elements_located((By.XPATH, '//*[@data-testid="RemoveProductBtn_btn"]')))
        for element in elements:
             element.click()
    except:
        print("no more products available")
        break

#next step

I think you will be always able to click one element and then page will refreshed. so use this code block.

while True:
    try:
        elements=WebDriverWait(self.driver, 20).until(EC.presence_of_all_elements_located((By.XPATH, '//*[@data-testid="RemoveProductBtn_btn"]')))
        elements[0].click()        
    except:
        print("no more products available")
        break
