What is XML’s importance to Web Design?

XML is at the core of all web development today. It’s used in popular websites, including popular social media outlets, and is also used in much of IBM’s web development. XML helps information systems share system data. While HTML tells browsers how to present information for human use, XML is a meta language giving meaning to data that other applications can use – in short, information about other information. XML is application and platform independent and caters to various types of data. Using XML is incredibly handy for web development purposes – it’s incredibly easy to read and understand, it’s supported by a large number of platforms and is used across open standards.
