主div类：Pitch-sc-1mctasb-0 mPWDj，有4个div子元素，在这些子元素下还有更多的子元素。我想分别获取XPATH并将它们显示在正确的div父项下

Answer 1

您应该使用find_elements()来获取元素列表

注意：在遍历元素列表时，会得到StaleElementReferenceException，因此必须处理异常

供您使用：

lst_of_el = driver.find_elements_by_css_selector("div[class^='Pitch-sc'] div")

Answer 2

可以使用WebElement.<Locator Strategy>("<Locator>")方法获取所有子元素。如果您执行以下操作，则与共享HTML类似：

parent = driver.find_element_by_xpath("//div[@class='Pitch-sc-1mctasb-0 mPWDj']") #As class has compound string css selector is failing, used xpath
children = parent.find_elements_by_tag_name("div")
print(len(children))

因为类名为'Pitch-sc-1mctasb-0 mPWDj的div中总共有36个div。它将打印36

如果您只想筛选选择性的子div，请相应地修改您的定位器。如下所示，将只选择15个以data testid为标题的div：

parent = driver.find_element_by_xpath("//div[@class='Pitch-sc-1mctasb-0 mPWDj']")
children = parent.find_elements_by_xpath("//div[@data-testid='title']")
print(len(children))
