Selenium - 无法点击搜索结果中的链接

Question

我正在使用 Selenium 和 python 搜索关键字，然后在搜索结果中我尝试单击前 5 个 url 并从 p 标签获取数据，然后返回。所以基本上然后我存储来自这 5 个站点的数据。但不知何故，在搜索关键字后，我不会点击网址并获取数据。我不知道怎么了。这是我写的代码。请帮忙。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome(executable_path="E:\chromedriver\chromedriver.exe")
driver.get("https://www.google.com/")
print(driver.title)

driver.maximize_window()
time.sleep(2)

driver.find_element(By.XPATH, "//input[@name='q']").send_keys('selenium')
driver.find_element(By.XPATH, "//div[@class='FPdoLc tfB0Bf']//input[@name='btnK']").send_keys(Keys.ENTER)

a = driver.find_elements_by_xpath("//div[@class='g']/a[@href]")
links = []
for x in a:
    links.append(x.get_attribute('href'))
    link_data = []
for new_url in links:
    print('new url : ', new_url)
    driver.get(new_url)
    link_data.append(driver.page_source)

    b = driver.find_elements(By.TAG_NAME, "p")
    for data in b:
        print(data.text)

    driver.back()
    driver.close()

编辑： 在浏览链接时，它还包括来自“人们也问”的链接。我不想浏览这个框。我该怎么做？

Answer 1

如果你想使用 16 个左右的链接。

driver.get("https://www.google.com/")
print(driver.title)

driver.maximize_window()
time.sleep(2)

driver.find_element(By.XPATH, "//input[@name='q']").send_keys('selenium')
driver.find_element(By.XPATH, "//input[@name='btnK']").send_keys(Keys.ENTER)

a = driver.find_elements_by_xpath("//div[@class='g']/div/div/a")
links = []
for x in a:
    links.append(x.get_attribute('href'))
    link_data = []
for new_url in links:
    print('new url : ', new_url)
    driver.get(new_url)
    link_data.append(driver.page_source)

    b = driver.find_elements(By.TAG_NAME, "p")
    for data in b:
        print(data.text)

    driver.back()

Answer 2

链接的 xpath 错误，应该是：

"//div[@class='yuRUbf']/a[@href]"

如果你查看代码的相关部分，你会发现<a> 标签不是<div class="g"> 的子标签，而是<div class="yuRUbf"> 的子标签

<div class="g"><!--m-->
    <div class="tF2Cxc" data-hveid="CAkQAA" data-ved="2ahUKEwjphfjOoazuAhUO1VkKHVSkA_oQFSgAMAp6BAgJEAA">
        <div class="yuRUbf"><a href="https://www.healthline.com/nutrition/selenium-benefits"
                               data-ved="2ahUKEwjphfjOoazuAhUO1VkKHVSkA_oQFjAKegQICRAC"
                               ping="/url?sa=t&amp;source=web&amp;rct=j&amp;url=https://www.healthline.com/nutrition/selenium-benefits&amp;ved=2ahUKEwjphfjOoazuAhUO1VkKHVSkA_oQFjAKegQICRAC"><br>
            <h3 class="LC20lb DKV0Md"><span>7 Science-Based Health Benefits of Selenium - Healthline</span></h3>
            <div class="TbwUpd NJjxre"><cite class="iUh30 Zu0yb qLRx3b tjvcx">www.healthline.com<span
                    class="dyjrff qzEoUe"><span> › nutrition › selenium-benefits</span></span></cite></div>
        </a>
            ...
        </div>
    </div>
</div>

你也可以稍微改变一下你的搜索线，但不会改变整体效果：

driver.find_element_by_xpath("//input[@name='q']").send_keys('selenium', Keys.ENTER)
