2004-09-14: XML, the Extensible Markup Language, is a general-purpose markup
language for all applications that manipulate text. XML is derived
from an older standard known as SGML.
XHTML (which supersedes HTML) is one example of
a specific markup language which is complies with the rules of XML.
RSS is another such example. While XHTML is
the best-known example, XML can be used to represent almost any kind
of information. The existence of a standard markup language makes
it possible for anyone to write software that can successfully
extract specific information from any valid XML document.
See the
W3C Consortium website
for further information and the complete XML specification.
