如何让python上的selenium web驱动程序在以下页面的css选择器上查找元素？

我试图让selenium使用CSS选择器在web上抓取wiki页面的第一段

当我运行此代码时，它似乎只从原始网页中选择一个

而不是我正在寻找的，在这个例子中是“猫”

这方面的任何帮助都会很棒

browser = webdriver.Firefox(executable_path='D:\Import Files that I also want backed up\Jupyter Notebooks\Python Projects\Selenium\driverss\geckodriver.exe')
browser.get('https://en.wikipedia.org')

search_elem = browser.find_element_by_css_selector('#searchInput')

search_elem.send_keys('cats')
search_elem.submit()


results_elem = browser.find_element_by_css_selector('p')

print(results_elem.text)

---

要从wiki页面获取第一段文本，请导入

WebDriverWait（）

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

browser = webdriver.Firefox(executable_path='D:\Import Files that I also want backed up\Jupyter Notebooks\Python Projects\Selenium\driverss\geckodriver.exe')
browser.get('https://en.wikipedia.org')
search_elem = browser.find_element_by_css_selector('#searchInput')
search_elem.send_keys('cats')
search_elem.submit()
results_elem=WebDriverWait(browser,10).until(EC.visibility_of_element_located((By.CSS_SELECTOR,"div.mw-parser-output p:nth-of-type(3)")))
print(results_elem.text)

您的预期输出是什么？我想打印“cat”页面的第一段。但是当我使用css选择器时，我仍然只是在删除第一个“wikipedia.com”页面。即使我在“猫”的页面上。基本上，我希望能够在使用selenium搜索主题后从网页中进行刮取。如果我使用搜索栏删除代码，请参见此操作。但是，当我通过搜索cat进入cat页面时，如果您的页面需要更多时间加载，则需要从访问的第一个页面中选择css选择器。然后提供一些时间。在提交页面后睡眠（5）。让我知道这是怎么回事？
