Dynamic web pages, which change content based on user interactions, require specialized tools for data extraction, and Selenium is a preferred choice for scraping such pages due to its ability to handle JavaScript-generated content. The blog post discusses using Selenium with C# for scraping data from dynamic web pages, emphasizing the difference from static page scraping, which can be done with tools like HTMLAgilityPack. It provides a step-by-step guide on setting up a Selenium C# project in Visual Studio, including necessary packages and browser drivers, and demonstrates scraping examples on LambdaTest's YouTube channel and blog page. These examples showcase Selenium's ability to mimic user actions and extract data like video titles, views, upload times, and blog metadata. The post also highlights the importance of understanding a website's structure and using Selenium's FindElements and FindElement methods to locate and extract data effectively.
