如何在 python 上获取 selenium web 驱动程序以在以下页面的 ZC7A628CBA22E28EB17B5F5C6AE2A26 上查找元素？

Question

我试图让 selenium 到 web 使用 CSS 选择器刮掉维基页面的第一段。

当我运行此代码时，似乎只有 select 来自原始 web 页面

https://en.wikipedia.org

而不是我正在寻找的东西，在这种情况下是“猫”。

对此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)

output:

Adventure Time is an American fantasy animated television series created .....

从 wiki 页面获取第一段文本。Induce WebDriverWait()和visibility_of_element_located () 并遵循css选择器。

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)
