为什么selenium在列表中找到相同的元素，其中有不同的父元素

Question

我不明白它为什么会给我返回相同的元素？如果我只是在els中打印每个元素的outerHTML，就会发现它们都不一样。但是当我在下面运行代码时，它显示的是相同的。

import selenium
from selenium import webdriver
from selenium.webdriver.common.by import By

d = webdriver.Chrome('chromedriver-2')
d.get(link)

els = d.find_elements(By.XPATH, '//*[@class="c-product-row__td "]')
for q in els:
    el = q.find_element(By.XPATH, '//*[@class="c-product-row__symbol-h4"]')
    print(el.get_attribute('outerHTML'))

产出如下：

Answer 1

您总是得到相同的元素，因为

q.find_element(By.XPATH, '//*[@class="c-product-row__symbol-h4"]')

从页面开始查找与//*[@class="c-product-row__symbol-h4"] XPath定位器匹配的第一个元素。

要在(下面)特定元素中找到元素，您应该在.的前面添加一个点XPath

q.find_element(By.XPATH, './/*[@class="c-product-row__symbol-h4"]')

Answer 2

您看到的不是相同的元素，而是不同的元素，但是WebElements具有相同的文本，即MAM1F11Z11在通过Locator Strategy标识的<h4>标记中。

//*[@class="c-product-row__symbol-h4"]
