如何使用 python 中的硒查找 html 的 class 中是否存在元素

How to find whether an element is present or not in a class of html using selenium in python

我必须相同的划分类型:

1) 其中包含特定 class (tile-freeCancellation)

的划分
<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) 没有那个 class (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 class (tile-freeCancellation) 的元素是否存在于主要元素 (class tile-duration) 中?

我正在为这个程序使用 python3 并使用函数 find_element_by_class_name 来查找 main class

的元素

selenium returns 的元素对象有自己的 find_element_by_* 方法,将搜索限制在它们的后代中,因此您可以这样做:

# Get a reference to both of the main elements
elements = driver.find_elements_by_class_name('tile-duration')

# helper function for checking presence of inner element
def free_cancel_descendants(element):
    return element.find_elements_by_class_name('tile-freeCancellation')

# use it, e.g. to filter the divs:
free_main_divs = [el for el in elements if free_cancel_descendants(el)]

我的尝试-三元运算(if) or if or helper function as by @W. Cybriwsky

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select a div(motherelement) 然后在里面搜索。

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