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 us 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. 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. It also covers XSL (Extensible Stylesheet Language), necessary to ensure that your XML documents have a consistent look and feel across platforms. Although XML itself is complex, its basic concepts are simple. This small book acts both as a perfect tutorial for learning the basics of XML, and as a reference to the XML and XSL specifications.
