what is xml and what is it used for?
In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The W3C's XML 1.0 Specification and several other related specificationsâall of them free open standardsâdefine XML.
The Difference Between XML and HTML. 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.
