Extensible Markup Language (XML)

Extensible Markup Language (XML) lets you define and store data in a shareable manner. XML supports information exchange between computer systems such as websites, databases, and third-party applications.

What is XML?

• XML stands for eXtensible Markup Language
• XML is a markup language much like HTML
• XML was designed to store and transport data
• XML was designed to be self-descriptive
• XML is a W3C Recommendation

XML Does Not DO Anything

• It has sender information
• It has receiver information
• It has a heading
• It has a message body

XML and HTML were designed with different goals:

• XML was designed to carry data – with focus on what data is
• HTML was designed to display data – with focus on how data looks
• XML tags are not predefined like HTML tags are
