Full Definition of XML

:  a markup language with use and design similar to HTML but employing tags that indicate the logical structure in addition to the display specifications of the coded data

Origin of XML

X (from extensible) + markup language
First Known Use: 1989


noun    (Concise Encyclopedia)

Markup language developed to be a simplified and more structural version of SGML. It incorporates features of HTML (e.g., hypertext linking), but is designed to overcome some of HTML's limitations. For example, it is designed to be extensible (i.e., designed to allow the creation of customized markup tags), which HTML is not. It is also designed to represent data by meaning rather than by layout (as it is represented in HTML). Like SGML, it is a metalanguage (a language for dealing with languages); it allows users to create a language tailored specifically to their needs.
