Extensible Markup Language (XML) is the universal format for data on the Web. XML allows developers to easily describe and deliver rich, structured data from any application in a standard, consistent way. XML does not replace HTML; rather, it is a complementary format. For a set of XML tutorials and samples please visit W3Schools.

XHTML is an acronym for "eXtensible HyperText Markup Language",  a reformulation of HTML 4.0 as an XML 1.0 application. XHTML provides the framework for future extensions of HTML and aims to replace HTML in the future. For tutorials and sample XHTML code please visit W3Schools.

VRML stands for "Virtual Reality Modeling Language''. It allows to specify dynamic 3D scenes through which users can navigate with the help of a VRML browser. VRML scenes can be distributed over the World-Wide Web and browsed with special VRML browsers, most of which are plug-ins for Netscape or Internet Explorer. Please visit 3D Links for tutorials on VRML.
