This article takes a pragmatic look at XHTML, a markup language that effectively bridges the gap between the simplicity of HTML and the extensibility of XML. It also covers the essential features of the various flavors of XHTML and includes discussions of the language and a number of real-world applications.

Code samples illustrate this comparison in detail.
