How to scrape browser extension details from SwitchyOmega using Python?
Scraping details like browser extension names, versions, and descriptions from SwitchyOmega’s listing pages involves parsing structured HTML data. Python’s BeautifulSoup library is well-suited for static web pages, while Selenium is ideal for JavaScript-rendered content. Start by inspecting the page structure to locate where extension details are stored—usually within div or span tags with specific classes. If dynamic loading or pagination is involved, automation tools like Selenium can handle these interactions seamlessly. Additionally, handling request headers and using delay mechanisms helps avoid anti-scraping measures.Here’s an example of scraping extension details using BeautifulSoup:
import requests from bs4 import BeautifulSoup url = "https://example.com/switchyomega/extensions" headers = {"User-Agent": "Mozilla/5.0"} response = requests.get(url, headers=headers) if response.status_code == 200: soup = BeautifulSoup(response.content, "html.parser") extensions = soup.find_all("div", class_="extension-item") for extension in extensions: name = extension.find("h2", class_="extension-name").text.strip() version = extension.find("span", class_="extension-version").text.strip() description = extension.find("p", class_="extension-description").text.strip() print(f"Name: {name}, Version: {version}, Description: {description}") else: print("Failed to fetch extension details.")For dynamic content or infinite scrolling, Selenium can simulate user interactions to load and extract all extension details. How do you handle anti-scraping measures when working with dynamically updated pages?

When infinite scrolling is required, I use Puppeteer to scroll down iteratively and load more content until no additional movies are visible. This ensures complete data extraction.

Rotating user-agent headers and implementing request delays helps avoid detection. These small changes make the scraper appear more like a real user.
