To allow Web pages to be structured for automated processing, the World Wide Web Consortium (W3C) developed an enhancement to HTML. The result were two new languages; one was XSL (extensible Style Language), and the other was XML (extensible Markup Language), a system for defining, validating, and sharing document formats on the Web.
XML is best known to many bloggers as RSS (Rich Site Summary/Really Simple Syndication), which is actually a lightweight XML format used to share headlines and blog feeds. XML is fairly straightforward to use, once you understand its structure. It is a platform-independent way to represent data. Simply put, XML enables you to create data that can read by any application on any platform. You can even edit and create it by hand, because it is based on the same tag-based technology that underlies HTML. It also provides several different methods by which you can control the structure, and even the content, of your data. Once you begin to use XML, you'll also have questions about the best way to design your XML structures, but it doesn't have to be a complicated process.
