XML Notes

XML was designed to transport and store data.
HTML was designed to display data.


What is XML?
• XML stands for EXtensible Markup Language
• XML is a markup language 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
________________________________________
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.
