Python 当从表数据中通过 Xpath 搜索时，Selenium 除了期望值之外还返回空白值

要从网站HOOPSHYPE提取并打印player names，理想情况下，您需要将WebDriverWait归结为visibility_of_all_elements_located()，并且您可以使用以下Locator Strategies之一:

• 使用CSS_SELECTOR:

  driver.get("https://hoopshype.com/salaries/players/")
  print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "td.name > a")))])
  

• 使用XPATH:

  driver.get("https://hoopshype.com/salaries/players/")
  print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//td[@class='name']/a[text()]")))])
  

• 控制台输出:
