XML Interview Questions & Answers - Learning Mode

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. Extensible Markup Language (XML) is used to describe data. The XML standard is a flexible way to create information formats and electronically share structured data via the public Internet, as well as via corporate networks. XML is a way of adding intelligence to your documents. It lets you identify each element using meaningful tags and it lets you add information ("metatdata") about that element.
