While selenium offer parsing capabilities of its own, they are sub-par to what's available in python's ecosystem. With these contents at hand, we can finish up our project and parse related dynamic data: from parsel import Selector We've started a browser, told it to go to and wait for the page to load and retrieve the page contents. In this case, our condition is a presence of an element that we select through a CSS selector. Here, we are using a special WebDriverWait object which blocks our program until a specific condition is met. "prefs", ĭriver = webdriver.Chrome(options=options, chrome_options=chrome_options)Įlement = WebDriverWait(driver=driver, timeout=5).until(ĮC.presence_of_element_located((By.CSS_SELECTOR, 'div')) # configure chrome browser to not load images and javascriptĬhrome_options = webdriver.ChromeOptions() In Selenium, we can instruct the Chrome browser to skip image rendering through the chrome_options keyword argument: from selenium import webdriverįrom import WebDriverWait ![]() ![]() Options.add_argument("start-maximized") # ensure window is full-screenĭriver = webdriver.Chrome(options=options)Īdditionally, when web-scraping we don't need to render images, which is a slow and intensive process. Options.add_argument("-window-size=1920,1080") # set window size to native GUI size In Selenium, we can enable it through the options keyword argument: from selenium import webdriverįrom import Options However, often when web-scraping we don't want to have our screen be taken up with all the GUI elements, for this we can use something called headless mode which strips the browser of all GUI elements and lets it run silently in the background. If we run this script, we'll see a browser window open up and take us our twitch URL. To start with our scraper code let's create a selenium webdriver object and launch a Chrome browser: from selenium import webdriver
