无法通过selenium和python访问html元素

Question

我想通过selenium访问html元素。

这是我的代码：

url = 'https://finance.yahoo.com/quote/ABBV/analysis'
xpath_string = '//html//body//div[1]//main//section//section//section//article//section[7]//div[1]//section[1]//div//div//div[3]//div[1]//span[1]'
print('############# Kursziel (via Yahoo)')
print("URL (yahoo):",url)
print("XPath (yahoo):",xpath_string)
try:

    driver.get(url)
    raw_res = WebDriverWait(driver, delay).until(EC.presence_of_element_located((By.XPATH, xpath_string)))
    print("Raw res (yahoo): ", raw_res)

    // do stuff and return value

except Exception as e:
    // handle exception

我通过打开 DOM 树并单击元素上的“复制完整 XPath”，从开发工具获取 xPath。

我搜索的元素是平均值（来自研究分析->分析师价格目标）。

这个原理适用于其他网站，但不适用于这个网站。

我收到此错误：

URL (yahoo): https://finance.yahoo.com/quote/ABBV/analysis
XPath (yahoo): 
//html//body//div[1]//main//section//section//section//article//section[7]//div[1]//section[1]//div//div//div[3]//div[1]//span[1]

如果我缩短 XPath，最后一个起作用的是： '//html//body//div[1]//main'

但即使在这一点上，也存在一些握手错误（听起来像是 TCP 问题）：

如果我尝试使用开发工具控制台和 $x("") 命令访问相同的元素，它会起作用。所以一定是和驱动连接有关。

关于如何解决这个问题有什么想法吗？

Answer 1

您可以使用 CSS 选择器获取该值，

div.label.average > span.price
