Selenium Python：选择 class 中的所有项目并将它们放入列表中？

Question

有没有办法把某个class的所有元素放到一个列表中？例如：

<li class="Fruit">Apple</li>
<li class="Fruit">Orange</li>

我想将 Apple 和 Orange 放入列表中。

Answer 1

  driver.find_elements_by_class_name("Fruit")

查找元素 returns 符合给定条件的所有元素，此处为 class 名称，它 returns 列表

您可以将文本打印为：

https://selenium-python.readthedocs.io/locating-elements.html

elems = driver.find_elements_by_class_name("Fruit")
for elem in elems:
    print(elem.text)

或

elemsText = [i.text for i in driver.find_elements_by_class_name("Fruit")]
print(elemsText]

Answer 2

提取并打印文本，例如Apple、Orange 等来自所有 <li class="Fruit"> 使用 and python you can use either of the following :

• 使用class_name和get_attribute("textContent"):

  print([my_elem.get_attribute("textContent") for my_elem in driver.find_elements_by_class_name("Fruit")])
  

• 使用css_selector和get_attribute("innerHTML"):

  print([my_elem.get_attribute("innerHTML") for my_elem in driver.find_elements_by_css_selector(".Fruit")])
  

• 使用 xpath 和 text 属性：

  print([my_elem.text for my_elem in driver.find_elements_by_xpath("//*[@class='Fruit']")])

理想情况下你需要诱导 for visibility_of_all_elements_located() and you can use either of the following :

• 使用CLASS_NAME和get_attribute("textContent"):

  print([my_elem.get_attribute("textContent") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CLASS_NAME, "Fruit")))])
  

• 使用CSS_SELECTOR和get_attribute("innerHTML"):

  print([my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, ".Fruit")))])
  

• 使用 XPATH 和 text 属性：

  print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//*[@class='Fruit']")))])
  

• 注意：您必须添加以下导入：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
