在此示例中，我正在嘗試從藝術家那里收集所有 (5) 個社交媒體鏈接。目前，我的輸出只是最后一個（第五個）社交媒體鏈接。我正在使用硒，我知道這不是收集這些資料的最佳選擇，但我目前所知道的一切。請注意，我只為我的問題提供了相關代碼。提前感謝您的任何幫助/見解。

uj5u.com熱心網友回復：
問題不在于您的 XPath 運算式，而在于您的輸出代碼的（不存在的）串列處理。
您的代碼只輸出了結果 XPath 串列的最后一項。這就是為什么您只收到一個鏈接（這是最后一個）的問題。
因此，將代碼的輸出部分更改為
[...]
url = driver.get("https://soundcloud.com/flux-pavilion")
time.sleep(randint(3,4))
artist = []
try:
links = driver.find_elements_by_xpath('//*[@id="content"]/div/div[4]/div[2]/div/article[1]/div[2]/ul/li//a[@href]')
for elem in links:
artist.append(elem.get_attribute("href"))
except:
links = "none"
for link in artist:
print(link)
并且輸出將包含您想要的所有值（鏈接）：
driver = webdriver.Chrome(chrome_options=chrome_options)
