XML stands for Extensible Markup Language. You might think it would be “eXtensible Markup Language,” but it’s not. Odd acronym aside, XML rates inclusion in a book for beginning programmers because, as your software-development career (whether as a hobbyist sqor a professional) continues, you’ll inevitably run into XML in all sorts of places. It’s used to store documents, from the contents of a single web page to the contents of entire sets of encyclopedias. It’s also used to transmit data between applications, whether the servers running those applications are halfway around the world or in the same room. It’s even used (with Cascading Style Sheets) to display information in web browsers. Every company I’ve worked for over the last dozen years, and every application I’ve written (at least those applications more serious and substantial than Minesweeper), has made at least some use of XML.
