The arrival of support for XML--the Extensible Markup Language--in browsers and authoring tools has followed a long period of intense hype. Major databases, authoring tools (including Microsoft's Office 2000), and browsers are committed to XML support. Many content creators and programmers for the Web and other media are left wondering, "What can XML and its associated standards really do for me?" Getting the most from XML requires being able to tag and transform XML documents so they can be processed by web browsers, databases, mobile phones, printers, XML processors, voice response systems, and LDAP directories, just to name a few targets.In Learning XML, the author explains XML and its capabilities succinctly and professionally, with references to real-life projects and other cogent examples. Learning XML shows the purpose of XML markup itself, the CSS and XSL styling languages, and the XLink and XPointer specifications for creating rich link structures.The basic advantages of XML over HTML are that XML lets a web designer define tags that are meaningful for the particular documents or database output to be used, and that it enforces an unambiguous structure that supports error-checking. XML supports enhanced styling and linking standards (allowing, for instance, simultaneous linking to the same document in multiple languages) and a range of new applications.For writers producing XML documents, this book demystifies files and the process of creating them with the appropriate structure and format. Designers will learn what parts of XML are most helpful to their team and will get started on creating Document Type Definitions. For programmers, the book makes syntax and structures clear It also discusses the stylesheets needed for viewing documents in the next generation of browsers, databases, and other devices.

Although Learning XML covers XML rather broadly, it nevertheless presents the key elements of the technology with enough detail to familiarize the reader with this crucial markup language. This guide is brief enough to tackle in a weekend.
Author Erik T. Ray begins with an excellent summary of XML's history as an outgrowth of SGML and HTML. He outlines very clearly the elements of markup, demystifying concepts such as attributes, entities, and namespaces with numerous clear examples. To illustrate a real-world XML application, he gives the reader a look at a document written in DocBook--a publicly available XML document type for publishing technical writings--and explains the sections of the document step by step. A more simplified version of DocBook is used later in the book to illustrate transformation--a powerful benefit of XML.
The all-important Document Type Definition (DTD) is covered in depth, but the still-unofficial alternative, XML Schema, is only briefly addressed. The author makes liberal use of graphics, tables, and code to demonstrate concepts along the way, keeping the reader engaged and on track. Ray also goes deep into some discussion of programming XML utilities with Perl.
Learning XML is a very readable introduction to XML for readers with existing knowledge of markup and Web technologies. It meets its goals very well--to deliver a broad perspective of XML and its potential. --Stephen W. Plain
