What is XML?
Posted: Tue May 31, 2016 11:38 am
XML--the eXtensible Markup Language--is a self-descriptive, data definition language. It's similar to HTML, the language of the Web, but it's far more powerful because it's not limited to a static list of language constructs ("tags") that the language's authors supply. Instead, XML is extensible and dynamic: Programmers can define new types of data using XML and then describe that data so that others will know how to use it.
