python - 如何在python中使用selenium查找html类中是否存在元素

Question

我必须有相同的划分类型:

1)其中包含特定类的划分(tile-freeCancellation)

<p class="col col-md-6 tile-duration">
  <span id="activityDuration183909" class="tile-activity-duration">
    <span class="icon icon-time" aria-hidden="true"></span>
    <span class="alt">Duration</span>
    2d+ 
  </span>
  <span id="activityFreeCancellation183909" class="tile-freeCancellation">
    <span id="offerFreeCancellationIcon4" class="icon icon-success" aria-hidden="true"></span>
    <span id="offerFreeCancellationText4" class="tile-free-cancel"> Free cancellation </span>
  </span>
</p>

2) 没有该类 (tile-freeCancellation)

<p class="col col-md-6 tile-duration">
  <span id="activityDuration186022" class="tile-activity-duration">
    <span class="icon icon-time" aria-hidden="true"></span>
    <span class="alt">Duration</span>
    2d 
  </span>
</p>

有什么方法可以检查类(tile-freeCancellation)的元素是否存在于(类tile-duration)的主元素中？

我在这个程序中使用python3，并使用函数find_element_by_class_name来查找主类的元素

Answer 1

我的尝试-三元运算(if)或@W的if或辅助函数。赛布里夫斯基

if len(driver.find_elements_by_class_name("tile-freeCancellation"))>0:
    #do something
else:
    # do another

如果是嵌套元素，例如选择一个 div(母元素)，然后在其中搜索。

if len(motherelement.find_elements_by_class_name("tile-freeCancellation"))>0:
    #do something
else:
    # do another
