'The XML Pocket Reference' is both a handy introduction to XML terminology and syntax, and a quick reference to XML instructions, attributes, entities and datatypes. This small book acts as both a tutorial for learning the basics of XML, and as a reference to the XML and XSL specifications.
XML, the Extensible Markup Language, is the next-generation markup language for the web. It provides a more structured (and therefore more powerful) medium than HTML, allowing users to define new document types and stylesheets as needed. Although the generic tags of HTML are sufficient for everyday text, XML gives us a way to add rich, well-defined markup to electronic documents.
