python - 如何使用 Selenium 和 Python 定位元素并提取内部文本

Question

<span class="chr-UserDropdownItem-imageAndText">
    <img class="chr-UserDropdownItem-image" src="/slm/profile/image/264023573852/24.sp?version=1" alt="User Profile Avatar">
    <span class="smb-DropdownItem-text">
        <span>   test user   </span>
    </span>
</span>

通过查看上面的屏幕截图，请帮助我从 span 标记中提取唯一的 innerText 测试用户。

Answer 1

要提取文本测试用户，您必须为visibility_of_element_ located()引入WebDriverWait，并且可以使用以下任一 Locator Strategies :

• 使用 CSS_SELECTOR 和 get_attribute():

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "span.smb-DropdownItem-text>span"))).get_attribute("innerHTML"))
  

• 使用 XPATH 和 text 属性:

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "span[@class='smb-DropdownItem-text']>span"))).text)
  

• 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
