我正在使用 selenium 自動轉到各種網頁并下載 XML 檔案。這一直作業正常，但突然停止作業，這是由于硒無法找到該元素。我試過在 CSS 和 Xpath 中使用選擇器小工具。我試過直接從檢查面板復制，我試過在 selenium 上使用等待功能，直到元素完全顯示，但我沒有走運。
這是下載按鈕所在的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>
下載按鈕就在視頻上方，分數線上方。
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()

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()

uj5u.com熱心網友回復：
要定位可點擊元素而不是presence_of_element_located()，您需要為element_to_be_clickable()引入WebDriverWait，您可以使用以下任一定位器策略：
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：您必須添加以下匯入：
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，我剛剛意識到單擊其中一個元素會打開一個新視窗。問題解決。謝謝你們。
