使用 Python 在网页上选择适当的元素 - Selenium chromedriver

Question

我正在尝试编写需要在网页上打开两个框并获取正确电子邮件地址的脚本。 我相信我没有正确继承网页上的元素。 请在下面查看我的代码：

   try:
            WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "body > section > section > section > div.mapAndAttrs > p:nth-child(2)")))
            xxx = driver.find_element_by_css_selector("#titletextonly").text
            #Click on Reply button
            WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.reply-button.js-only"))).click()
            WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, 'body > section > section > header > div.reply-button-row > div > div.reply-info.js-only')))
            #target email address
            to = driver.find_element_by_css_selector("body > section > section > header > div.reply-button-row > div > div.reply-info.js-only > aside.reply-flap.js-captcha > ul > li.reply-email > p > a").text
        except:

这是我需要从中提取电子邮件的示例页面： https : //newyork.craigslist.org/fct/cto/d/ridgefield-2003-bmw-x5-30-xdrive/7212695001.html

电子邮件位于“回复”按钮，然后是另一个“显示电子邮件”按钮。

非常感谢任何指导。

您可以使用：

WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "body > section > section > section > div.mapAndAttrs > p:nth-child(2)")))
xxx = driver.find_element_by_css_selector("#titletextonly").text
#Click on Reply button
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.reply-button.js-only"))).click()
WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, 'body > section > section > header > div.reply-button-row > div > div.reply-info.js-only')))
#target email address
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'body > section > section > header > div.reply-button-row > div > div.reply-info.js-only > aside > ul > button'))).click()
WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'body > section > section > header > div.reply-button-row > div > div.reply-info.js-only > aside')))
texto = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'body > section > section > header > div.reply-button-row > div > div.reply-info.js-only > aside > ul > li.reply-email > p > a'))).text
