Presents a software engineering-focused view of XML, and investigates how XML can be used as a component integration technology much like COM or CORBA. After examining the differences between the Simple API for XML (SAX) and the Document Object Model (DOM), the authors look at navigation, XML schemas, and the XSL transformation language.

This reference for programmers and web developers covers all of XML along with related protocols and technologies. It is assumed that the reader has a basic understanding of XML. The authors are both with DevelopMentor's technical staff. c. Book News Inc.
XForms offer a more straightforward way to handle user input. This handbook presents a thorough explanation of the XForms technology and shows how to tae advantage of its functionality.
As a developer new to Web Services, how do you make sense of this emerging framework so you can start writing your own services today? This concise book gives programmers both a concrete introduction and a handy reference to XML web services, first by explaining the foundations of this new breed of distributed services, and then by demonstrating quick ways to create services with open-source Java tools.Web Services make it possible for diverse applications to discover each other and exchange data seamlessly via the Internet. For instance, programs written in Java and running on Solaris can find and call code written in C# that run on Windows XP, or programs written in Perl that run on Linux, without any concern about the details of how that service is implemented. A common set of Web Services is at the core of Microsoft's new .NET strategy, Sun Microsystems's Sun One Platform, and the W3C's XML Protocol Activity Group.In this book, author Ethan Cerami explores four key emerging technologies: XML Remote Procedure Calls (XML-RPC) SOAP - The foundation for most commercial Web Services development Universal Discovery, Description and Integration (UDDI) Web Services Description Language (WSDL) For each of these topics, Web Services Essentials provides a quick overview, Java tutorials with sample code, samples of the XML documents underlying the service, and explanations of freely-available Java APIs. Cerami also includes a guide to the current state of Web Services, pointers to open-source tools and a comprehensive glossary of terms.If you want to break through the Web Services hype and find useful information on these evolving technologies, look no further than Web Services Essentials.
Extensible Markup Language (XML) has been perhaps the biggest buzzword in application development for several years and now Microsoft has taken XML into the core of its .NET Framework. This book is aimed at teaching XML (and related technologies such as XPath, XSLT, and XML Schema) to beginning and intermediate Visual Basic .NET developers who want to understand what all the fuss is about.
The XML Pocket Reference, 2nd Edition, is both a handy introduction to XML terminology and syntax, and a quick reference to XML instructions, attributes, entities, and datatypes. The new edition introduces information on XSLT (Extensible Stylesheet Language Transformations) and Xpath.
Replacing DTDs (Document Type Definitions) as the way in which XML documents are described and validated, XML schemas are essential for ensuring the accuracy and security of information in B2B transactions and other XML applications. This how-to guide employs extensive examples and source code to help developers and programmers get quickly up to speed on the practical application of this important technology. With in-depth explanations for each example, XML expert Mike Fitzgerald acquaints readers with coding structures, then moves to more advanced topics, including unique element and attribute values, keys, and how to use schemas with HTML. Like the other books in the series, this guide features comprehensive appendices listing all the datatypes and data facets, code indexes, and other time-saving features.
Offering a distinctive approach, this book will teach readers not only how to use COM but how to think in COM. COM can greatly improve the efficiency of applications, but COM fluency is a difficult task. The book is a top resource for developers who need to make the transition from superficial understanding to deep knowledge.
If you need to create or use formal descriptions of XML vocabularies, the W3C's XML Schema offers a powerful set of tools for defining acceptable document structures and content. An alternative to DTDs as the way to describe and validate data in an XML environment, XML Schema enables developers to create precise descriptions with a richer set of datatypes?such as booleans, numbers, currencies, dates and times?that are essential for today?s applications.Schemas are powerful, but that power comes with substantial complexity. This concise book explains the ins and outs of XML Schema, including design choices, best practices, and limitations. Particularly valuable are discussions of how the type structures fit with existing database and object-oriented program contexts. With XML Schema, you can define acceptable content models and annotate those models with additional type information, making them more readily bound to programs and objects. Schemas combine the easy interchange of text-based XML with the more stringent requirements of data exchange, and make it easier to validate documents based on namespaces.You?ll find plenty of examples in this book that demonstrate the details necessary for precise vocabulary definitions. Topics include: Foundations of XML Schema syntax Flat, "russian-doll", and other schema approaches Working with simple and complex types in a variety of contexts The built-in datatypes provided by XML Schema Using facets to extend datatypes, including regular expression-based patterns Using keys and uniqueness rules to limit how and where information may appear Creating extensible schemas and managing extensibility Documenting schemas and extending XML Schema capabilities through annotations In addition to the explanatory content, XML Schemaprovides a complete reference to all parts of both the XML Schema Structures and XML Schema Datatypes specifications, as well as a glossary. Appendices explore the relationships between XML Schema and other tools for describing document structures, including DTDs, RELAX NG, and Schematron, as well as work in progress at the W3C to more tightly integrate XML Schema with existing specifications.No matter how you intend to use XML Schema - for data structures or document structures, for standalone documents or part of SOAP transactions, for documentation, validation, or data binding ? all the foundations you need are outlined in XML Schema.
