for循环存在于硒过早 - DOM对象上运行时改变

Question

我想遍历html元素在网页中删除它们。对于一个实例在购物车中的项目太多（这不是购物车，虽然）。

项目数是> 50。

但是，单击第一个项目后退出循环下，任何以为我失去了什么？

for i in  range(0, len(x)):
        time.sleep(2)
        if x[i].is_displayed():
            print(i)


            pageClicked = WebDriverWait(driver, 2).until(
                ec.element_to_be_clickable((By.XPATH,
                                             "/html/body/div/div/div/div/router-view/div[1]/div/div[1]")))

            pageClicked.click()

            x[i].click() #removes the item

            """This is hardcoded part, TODO remove this """
            removalConfirm = WebDriverWait(driver, 2).until(
                ec.element_to_be_clickable((By.XPATH, "/html/body/ux-dialog-container/div/div/ux-dialog/ux-dialog-body/form/div[2]/button[1]")))
            #
            """"remove from the wishlist """
            removalConfirm.click() #receive confirmation
            i=i+1

在飞行的DOM对象改变了，所以我不得不重新夺回DOM对象。下面的工作。

 x = driver.find_elements_by_id(
                ObjectManager().getObjectIdentifierValue(driver, "Patron", "WishlistPage", "wishListCloseAll"))

            #print(len(x))

            for i in  range(0, len(x)-1):
                time.sleep(2)
                """Since the dom objects change on the fly, they need to named"""
                x = driver.find_elements_by_id(
                    ObjectManager().getObjectIdentifierValue(driver, "Patron", "WishlistPage", "wishListCloseAll"))

                #print('lenght of x', len(x))


                if  x[i].is_displayed():
                    if x[i].is_displayed():
                        x[i].click()
                       #print('x', x[i])

                        """This is hardcoded part, TODO remove this """
                        removalConfirm = WebDriverWait(driver, 2).until(
                            ec.element_to_be_clickable((By.XPATH, "/html/body/ux-dialog-container/div/div/ux-dialog/ux-dialog-body/form/div[2]/button[1]")))
                        #
                        """"remove from the wishlist """
                        removalConfirm.click()
                        i=i
                        #print(i)

                time.sleep(2)
