What is XML?

XML, eXtensible Markup Language, is the standard way to identify and describe data on the web. It is widely implementable and easy to deploy.

XML is a human-readable, machine-understandable, general syntax for describing hierarchical data, applicable to a wide range of applications, databases, e-commerce, Java, web development, searching, and so on.

Custom tags enable the definition, transmission, validation, and interpretation of data between applications and between organizations.
