未找到元素-Selenium-Python

Question

我尝试访问曼联主场的结果，但无法访问。。这是网站页面下面是该页面的一段 HTML 代码：<div id="g_1_l2dtbMED" title="Click for match detail!" class="event__match event__match--static event__match--last event__match--oneLine"><div class="event__time">04.10. 17:30</div><div class="event__participant event__participant--home"><svg class="card___2ip_DLm icon--redCard icon--redCard-first icon--redCard-last"><title></title><use xlink:href="/res/_fs/build/symbols.f1bc6b2.svg#card"></use></svg>Manchester Utd</div><div class="event__scores fontBold"><span>1</span>&nbsp;-&nbsp;<span>6</span></div><div class="event__participant event__participant--away fontBold">Tottenham</div><div class="event__part">(1&nbsp;-&nbsp;4)</div><span class="wld wld--l" title="Loss">L</span></div>我搜索解析的结果是“L”，位于 balise 中<span>。这是我尝试解析它所做的代码：driver = webdriver.Chrome()url = "https://www.flashscore.com/team/manchester-united/ppjDR086/results/"driver.get(url)Team = 'manchester Utd'results = WebDriverWait(driver, 20).until(EC.find_elements((By.XPATH,"//div[@class='event__participant--home' and contains(text(),'"+ Team +"')]//ancestor::div/span")))print(len(results))但这在 20 秒后（即搜索时间限制）给我抛出了异常“TimeoutException”。

Answer 1

您正在寻找的定位器是

//div[contains(@class,'event__participant--home')][text()='Manchester Utd']//following-sibling::span[1]

^ find a DIV that contains the class indicating a home game

                                                  ^ that also contains the team name

                                                                           ^ then find the first sibling SPAN that follows

该定位器将找到仅包含主场比赛的 L、W、D 等元素。

如果您要等待元素，您将需要等待可见，而不是存在。存在是指元素仅位于 DOM 中但不一定可见。如果要从页面上刮掉文本，则需要等待可见。您可以使用EC.visibility_of_all_elements_located(). 请参阅文档。如果您尝试在它们存在但不可见时抓取页面，则会引发异常。

您更新的代码如下

driver = webdriver.Chrome()

url = "https://www.flashscore.com/team/manchester-united/ppjDR086/results/"

driver.get(url)

Team = 'Manchester Utd'

results = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH,"//div[contains(@class,'event__participant--home')][text()='" + Team + "']//following-sibling::span[1]")))

print(len(results))

Answer 2

试试这个 xpath-

//div[contains(text(),'Manchester Utd')]/following-sibling::span
