Today,we gonna learn about XML XMLis another language of computer rather than HTML. XML is Extensible Markup Language. It was designed to describe data and focus what data is. It is more similar to HTML but, it is difference.
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
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.
XML Does Not DO Anything
The following example is a note to Tove, from Jani, stored as XML:
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>
But still, this XML document does not DO anything. It is just information wrapped in tags. Someone must write a piece of software to send, receive or display it.
Okay,guys....we need rest.!!..see you soon...
