XML (eXtensible Markup Language)


What Is XML? The Main Differences between XML and HTML XML Does Not Do Anything.
XML was not designed to do anything. It may be hard to understand, but XML does not do anything. XML is created to structure, store, and to send information. The example below 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>
The note has a header and a message body. It also has sender and receiver information. But still, this XML document does not do anything. It is just pure information wrapped in XML tags. Someone must write a piece of software to send, receive, or display it.

      The pine tar, the resin, the grass, the dirt.    
      And that’s just in the hot dogs.
