我正在嘗試使用 ChromeDriver 從以下 html 代碼中提取值“/mva/library/20120730/93135a040s.gif”：目前，我的代碼：is_black_white = driver.find_elements_by_xpath("http://div[@class='aj cw cy db ImgCaptionCntnrHover']/img[@data-filterwithidind='True']")x = is_black_white[0].get_attribute("title src")print(x)返回“無”。我感覺我已經(jīng)很接近了。任何幫助將非常感激！謝謝！

xpath 不正確。您可以嘗試這個解決方案。請注意，有一個雙斜杠表示任何帶有 img 標(biāo)簽的子節(jié)點。
WebDriverWait(driver, 30).until(EC.presence_of_all_elements_located((By.XPATH, "//div[@class='aj cw cy db ImgCaptionCntnrHover']//img")))
is_black_white = driver.find_elements_by_xpath("//div[@class='aj cw cy db ImgCaptionCntnrHover']//img")
print(len(is_black_white))
x = is_black_white[0].get_attribute("src")
print(x)
#Prints all the src urls
for ele in is_black_white:
print(ele.get_attribute("src"))
輸出：
