2.What is XML?
XML stands for EXtensible Markup Language
XML is a markup language much like HTML
XML was designed to describe data
XML tags are not predefined. You must define your own tags
XML uses a Document Type Definition (DTD) or an XML Schema to describe the data
XML with a DTD or XML Schema is designed to be self-descriptive
XML is a W3C Recommendation
3.XML vs. HTML
XML is not a replacement for HTML. XML and HTML were designed with different goals:
XML was designed to describe data and to focus on what data is. HTML was designed to display data and to focus on how data looks.
HTML is about displaying information, while XML is about describing information.

XML was created to structure, store and to send information.
The following example is a note to Kamal from Jani, stored as XML:

6.XML Syntax
Simple xml file:

7.XML Syntax
The first line in the document - the XML declaration - defines the XML version and the character encoding used in the document.
The next line describes the root element of the document (like it was saying: "this document is a note"):
Next 4 lines describes 4 child elements of the root (to, from, heading, and body)
And finally the last line defines the end of the root element:
8.XML Syntax
All XML Elements Must Have a Closing Tag.
XML Tags are Case Sensitive.
XML Elements Must be Properly Nested.
