使用 CSS 选择器从网页中提取数据 - Selenium Python

Question

我想从戴尔的网站上提取一些我对我的设备感兴趣的日期。我尝试使用下载网页，urllib但它受验证码保护，我现在无法绕过它。现在我使用Selenium打开浏览器，手动解决capthca，然后自动打开页面并提取日期。问题是 css 选择器返回了一些奇怪的元素而不是所需的输出我的代码：from selenium import webdriverimport timedriver = webdriver.Chrome()def scrape(codes):    dates = []    for i in range(len(codes)):        driver.get("https://www.dell.com/support/home/us/en/19/product-support/"                   "servicetag/%s/warranty?ref=captchasuccess" % codes[i])    # Solve captcha manually        if i == 0:            print("You now have 120\" seconds to solve the captcha")            time.sleep(120)            print("120\" Passed")    # Extract data        expdate = driver.find_element_by_css_selector("#printdivid > div > div.not-annotated.hover > table:nth-child(3) > tbody > tr > td:nth-child(3)")        print(expdate)    driver.close()codes = ['1FMR762', '15FDBG2', '10V8YZ1']scrape(codes)预期输出：June 22, 2018October 15, 2017April 19, 2017给定输出：<selenium.webdriver.remote.webelement.WebElement (session="d83af0f7a3a9c79307d2058f863a7ecb", element="0.21873872382745052-1")><selenium.webdriver.remote.webelement.WebElement (session="d83af0f7a3a9c79307d2058f863a7ecb", element="0.06836824093097027-1")><selenium.webdriver.remote.webelement.WebElement (session="d83af0f7a3a9c79307d2058f863a7ecb", element="0.6642161898702734-1")>
