python-3.x - 如何迭代 Selenium 和 Python 中的元素？

Question

我试图通过迭代此 HTML 的 li 列表来获取 span 标记内的文本:

<ol class="KambiBC-event-result__score-list">
    <li class="KambiBC-event-result__match">
        <span class="KambiBC-event-result__points">1</span>
        <span class="KambiBC-event-result__points">1</span>
    </li>
</ol>

但我收到错误

AttributeError: 'list' object has no attribute 'find_element_by_class_name'

在我的代码上:

meci = driver.find_elements_by_class_name('KambiBC-event-result__match')

for items in meci:

 scor = meci.find_element_by_class_name('KambiBC-event-result__points')


 print (scor.text)

Answer 1

您没有在循环内使用项目。你的循环应该是

meci = driver.find_elements_by_class_name('KambiBC-event-result__match')

for items in meci:
    scor = items.find_element_by_class_name('KambiBC-event-result__points')
    print(scor.text)

meci.find_element_by_class_name 应该是 items.find_element_by_class_name

Selenium 4 更新

正如本文中提到的Stack Overflow post ，从 Selenium 4 开始，find_element_by_* 方法已被弃用。因此，解决方案需要修改如下:

from selenium.webdriver.common.by import By

meci = driver.find_elements(By.CLASS_NAME, 'KambiBC-event-result__match')

for items in meci:
    scor = items.find_element(By.CLASS_NAME, 'KambiBC-event-result__points')
    print(scor.text)
