Scraping user agent profiles from Dolphin Anty involves extracting structured data such as browser versions, operating systems, and device types. Ruby, with its Nokogiri library, is a great choice for scraping static content. For dynamic content that uses JavaScript to render data, integrating Ruby with Capybara and Selenium provides an effective solution. Start by analyzing the webpage structure using developer tools to locate the relevant tags containing the user agent data. Pagination or infinite scrolling can also be handled with browser automation.Here’s an example using Nokogiri to scrape static data:require 'nokogiri'require 'open-uri'url 'https://example.com/dolphin-anty/user-agents'doc Nokogiri::HTML(URI.open(url))doc.css('.user-agent-item').each do |item| agent_name item.css('.agent-name').text.strip os item.css('.agent-os').text.strip browser item.css('.agent-browser').text.strip puts "Agent: #{agent_name}, OS: #{os}, Browser: #{browser}"endFor dynamic pages, Capybara can simulate user actions, such as scrolling or clicking, to load additional data. Proper error handling and retries ensure smooth operation for large datasets. How do you ensure your scraper adapts to frequent layout changes in a site like Dolphin Anty?

For pagination, I usually write a loop that follows “Next Page” links until there are no more pages to scrape. It ensures I capture all movies listed on the site.
