With the successful implementation of XML Schema, developers are learning how to increase productivity, improve software reliability, minimize development time, and decrease time to market. This in-depth reference is an all-in-one resource designed to help developers leverage the power and potential of XML schemas by offering a complete roadmap to their creation, design, and use.

This authoritative reference and tutorial is filled with practical insights and detailed examples. The book begins by providing a conceptual introduction to XML Schema. From there, coverage shifts to the W3C Schema Recommendation and how to apply schemas to specific business goals. The authors provide insight and instruction throughout on integrating XML schemas into existing technologies such as .NET, Java, Visual Basic, Oracle, and more. The book concludes with a complete case study designed to reinforce and illustrate material covered.

Additional topics include:

• Applications for schemas
• Simple and complex types
• XML schema processing and validation
• Namespaces in XML
• Using schemas with DOM and SAX
• XML schema document syntax
• XML Information Sets
• XML Schema applications of XPath

XML is a powerful cross-platform mark-up language which has readily been adopted as a standard in many spheres of web and software development. Real benefits include its ease of integration into existing systems, the simplicity of using it in object-oriented environments and its wide applicability. Chris Bates shows how to use XML in modern software developments and backs up a thorough treatment of its key points with clear, practical examples.
Programmers and developers wanting both A-Z coverage and a practical how-to, will find stepwise guidance on:
creating data, storage formats, implementing interfaces, providing a wireless protocol in distributed applications (SOAP), and creating intermediate data formats on the web.
Chris Bates provides live code in Java to show how XML can be employed in the development of applications and also provides details of how XML parsers work. You will learn more than simply how XML operates. You'll gain insight and understanding of the concepts, their importance and their application. Problems and exercises are provided and make the book ideal for self-study or classroom situations. With an accompanying website containing code samples and links to important web-sites, XML in Theory and Practice is a must-have primer on the subject.

xHTML is a programming language that is used to provide information services to portable wireless devices. This book explains how and why companies use xHTML to develop and provide information services to mobile communication devices. xHTML protocols and scripts are used to create web pages that can efficiently and reliably communicate with mobile communication devices.. This book explains what is xHTML Basic, when to use it, and why it is important to learn. You will discover how the xHTML Basic language was developed and the types of applications that benefit from xHTML Basic programs. The basic programming structure of xHTML Basic is described along with the basic commands including links, images, and special symbols that are used. An introduction to scripting is included and how to create advanced services and features using xHTML Basic programming. You will learn the similarities and difference of xHTML Basic to other communication languages including WML and HTML. You will also learn how to write and simulate xHTML Basic programs. Explained is the operation of WAP servers and how to publish xHTML Basic programs to servers to allow them to be accessed on the web. Also described is how xHTML Basic is being used and integrated with WML and WMLScript to ensure xHTML evolves to meet future communication needs.

XSLT Quickly is, quite obviously, for anyone who needs to learn XSLT quickly. This book has two main goals: to familiarize the reader with the portions of XSLT that he/she will use eighty per cent of the time, and to provide a "cookbook" approach to learning additional techniques as they are needed. Part One is a step-by-step tutorial that brings the reader up to speed on the basic concepts and document manipulation techniques necessary for the most common XSLT tasks. More importantly, it represents the foundation on which the understanding of everything in Part Two is built. Part Two is a cookbook--a task-oriented user's guide to various issues one may meet in tackling XSLT. This portion of the book is organized by the goals of XSLT tasks (converting elements to attributes, reading in multiple documents at once, etc.). This makes it far easier for readers who don't already know XSLT to quickly find the solutions to their stylesheet development problems. XSLT Quickly also includes a glossary, a quick reference section for XSLT syntax, and a quick reference for using the popular XSLT processors.

Referring to specific information inside an XML document is a little like finding a needle in a haystack: how do you differentiate the information you need from everything else? XPath and XPointer are two closely related languages that play a key role in XML processing by allowing developers to find these needles and manipulate embedded information. XPath describes a route for finding specific items by defining a path through the hierarchy of an XML document, abstracting only the information that's relevant for identifying the data. XPointer extends XPath to identify more complex parts of documents. The two technologies are critical for developers seeking needles in haystacks in various types of processing.

XPath and XPointer fills an essential need for XML developers by focusing directly on a critical topic that has been covered only briefly. Written by John Simpson, an author with considerable XML experience, the book offers practical knowledge of the two languages that underpin XML, XSLT and XLink. XPath and XPointer cuts through basic theory and provides real-world examples that you can use right away.
