如何在 python 上獲取 selenium web 驅動程序以在以下頁面的 ZC7A628CBA22E28EB17B5F5C6AE2A26 上查找元素？

Question

我試圖讓 selenium 到 web 使用 CSS 選擇器刮掉維基頁面的第一段。

當我運行此代碼時，似乎只有 select 來自原始 web 頁面

https://en.wikipedia.org

而不是我正在尋找的東西，在這種情況下是“貓”。

對此的任何幫助都會很棒！

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 .....

從 wiki 頁面獲取第一段文本。Induce WebDriverWait()和visibility_of_element_located () 並遵循css選擇器。

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)
