  6. Introduction to XML • What is XML? • XML stands for EXtensible Markup Language • XML is a markup language (tag-based) much like HTML • XML was designed to carry data, not to display data • XML tags are not predefined. You must define your own tags • XML is designed to be self-descriptive • XML is a W3C Recommendation

  8. Introduction to XML • What are some drawbacks of XML? • Not good for storing large amounts of data • Performance can be slower than other methods of storing and retreiving data • Might not be the best format for representing certain data types, like images and other binary data.

  9. Introduction to XML • The Difference Between XML and HTML • XML is not a replacement for HTML. • XML and HTML were designed with different goals: • XML was designed to transport and store data, with focus on what data is. • HTML was designed to display data, with focus on how data looks. • HTML is about displaying information, while XML is about carrying information.

  10. Introduction to XML • XML documents must be “well-formed” • Always have a single root tag • Tags must be properly nested, empty tags always end with /> • Attributes values must be inside quotes, cannot be minimized. • XML documents can be “valid”
