XML (eXtensible Markup Language) is a set of syntax rules and guidelines for defining text-based markup languages. XML languages have a number of uses including:
• Exchanging information
• Defining document types
• Specifying messages
Information that is expressed in a structured, text-based format can easily be transmitted between, transformed, and interpreted by entities that understand the structure. In this way XML brings the same cross-platform benefits to information exchange as the JavaTM programming language has for processing.
