从这部分 html 中使用的正确元素是什么？

Question

我正在使用 selenium 自动转到各种网页并下载 XML 文件。 这一直工作正常，但突然停止工作，这是由于硒无法找到元素。 我尝试使用带有 CSS 和 Xpath 的选择器小工具。我试过直接从检查面板复制，我试过在 selenium 上使用等待功能，直到元素完全显示，我没有运气。

这是下载按钮所在的html

<div class="video-playlist-xml" data-reactid=".2.0"><a href="#" data-reactid=".2.0.0"><i class="icon-download-xml-green" data-toggle="tooltip" data-placement="top" title="" data-original-title="Download xml file of the match" data-reactid=".2.0.0.0"></i></a></div>

下载按钮就在视频的上方，得分线的上方。

for x in range(number_of_clicks):
   driver = webdriver.Chrome(executable_path=r'C:\Users\James\OneDrive\Desktop\webdriver\chromedriver.exe',options = options)
   driver.get('https://football.instatscout.com/teams/978/matches')
   time.sleep(10)
   print("Page Title is : %s" %driver.title) 
   WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"#team-table1 > div.table-scroll-inner > div.team-stats-wrapper.team-stats-wrapper_no-vertical-scroll > table > tbody > tr:nth-child(" +str(x+1) + ") > td:nth-child(1) > div > div.styled__MatchPlay-sc-10ytjn2-1.hkIvhi > i"))).click()

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.video-playlist-xml > a[href] > i.icon-download-xml-green[data-original-title='Download xml file of the match']"))).click()
   chks = driver.find_elements_by_css_selector("#players > div.control-block > div.control-block__container.control-block__container--large > button")
   for chk in chks:
       chk.click()
       time.sleep(15)
       driver.quit()

Answer 1

要定位 可点击 元素而不是 presence_of_element_located()，您需要为 element_to_be_clickable() 引入 WebDriverWait，您可以使用以下任一 Locator Strategies ：

• 使用CSS_SELECTOR：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.video-playlist-xml > a[href] > i.icon-download-xml-green[data-original-title='Download xml file of the match']"))).click()
  

• 使用XPATH：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='video-playlist-xml']/a[@href]/i[@class='icon-download-xml-green' and @data-original-title='Download xml file of the match']"))).click()
  

• 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

愚蠢的是，我刚刚意识到单击其中一个元素会打开一个新窗口。问题解决了。谢谢各位。
