XML vs. JSON. Which one should be used and preferred?

XML

• XML stands for eXtensible Markup Language.
• It is a platform independent language
• XML is designed to carry data, not to display data (HTML is used to display data)
• XML tags are user defined and are case sensitive

JSON

• JSON stands for JavaScript Object Notation
• JSON is language independent
• JSON is lightweight, faster and easier to parse than XML
• It is derived from the JavaScript
• When data is encoded in XML, the result is typically larger than an equivalent encoding in JSON, mainly because of XML's closing tags.
• JSON has all of the advantages of XML + it is much better suited to data-interchange, as XML is not well suited to data-interchange.
