How can I use Selenium with headless browsers for web scraping?

You can use Selenium with headless browsers like Chrome or Firefox by setting the appropriate options. For example, in Python, you can use webdriver.ChromeOptions() to set the headless mode.

What are the advantages of using headless mode?

Headless mode allows for faster execution since it doesn't render the UI. It's also useful for running tests in environments without a display.

Can you provide a sample code snippet?

Sure! Here's a simple example:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.headless = True

driver = webdriver.Chrome(options=options)
driver.get('http://example.com')
print(driver.title)
driver.quit()

Are there any limitations to using headless browsers?

Yes, some limitations include potential issues with JavaScript-heavy sites and the lack of visual debugging.
