This article explains why XML Schema beats DTDs hands-down for data. It looks at four features of XML Schema that are particularly suited to data representation, and shows some examples of each. Code samples include XSD schemas and schema fragments.

XML Viewer for Java is a Java application that enables viewing XML data from various perspectives such as the source of the XML, the DTD for the XML, the hierarchical structure of the XML data. It displays any well-formed XML document.

Based on an analysis of several large XML projects, this article examines how to make effective and efficient use of DOM in Java. The DOM offers a flexible and powerful means for creating, processing, and manipulating XML documents, but it can be awkward to use and can lead to brittle and buggy code. Author Parand Tony Daruger provides a set of Java usage patterns and a library of functions to make DOM robust and easy to use.

This article describes how an XSLT processor, in this case the author's open-source Saxon, actually works. Although several open-source XSLT implementations exist (see Resources), no one, as far as we know, has published a description of how they work. This article is intended to fill that gap. It describes the internal workings of Saxon, and shows how this processor addresses XSLT optimization.

XSL Formatting Objects Composer (XFC) is a typesetting and display engine that implements a substantial portion of XSL Formatting Objects (FO), which became a W3C Recommendation on October 15, 2001. XSL FO is an XML language for typesetting, printing, or displaying any of the world's written languages.

The editor takes as input a given DTD, and automatically builds a palette containing the elements defined in the DTD. Users can thus create/edit/expand any document derived from that DTD, by using a visual tree-directed paradigm. The visual paradigm requires a minimum learning curve as only valid constructs/elements are presented to the user in a context-sensitive palette.

XML Security Suite is a tool that provides security features such as digital signature, encryption, and access control for XML documents. These features are beyond the capability of transport-level security protocols such as Secure Sockets Layer (SSL). The goals in creating this technology were to contribute to standards development by providing sample implementations and to supply advanced technologies to partners and developers and to gather their input.

A Sample Chapter from Early Adopter VoiceXML. This chapter examines the use of the Extensible Stylesheet Language for Transformations (XSLT) as a tool for the generation of VoiceXML. I intend to illustrate a complete, end-to-end example of implementing a voice interface for a client-server database via XML and XSL. The case study will demonstrate the power of XSL for simultaneously delivering multiple interfaces to the same data by developing HTML and WML front-ends also.

In this tutorial, selected XML features are demonstrated on many examples which can be downloaded for off-line use.

Here you will find XML related materials (both basic and advanced tutorials and references about XSLT, XML, DTD, Mozilla, CSS, schemas, regular expressions, etc.) which can be downloaded for off-line use.

In this tutorial, selected XPath features are demonstrated with many examples and pictures which can be downloaded for off-line use.

DTD is described in XML 1.0 standard. In this tutorial basic DTD features are demonstrated on many examples which can be downloaded for off-line use.

Even during these early stages of the evangelism of Web services, customers have already begun to ask how this technology differs from CORBA. Isn�t it just another form of distributed computing? In this installment of the Web services architect, Dan Gisolfi offers a brief overview of the differences between SOAP, DCOM, and CORBA and suggests a value proposition for Web services within the distributed computing realm.

E-business is driving the merging of web, IT and object technologies to form the foundations of a new architecture, Web Services. This classic Wrox compendium covers the broad spectrum of XML based technologies that will be used in Web Services and is for anyone involved in developing commercial business-oriented distributed applications. Topics covered: This book covers: The architecture of Web Services - past, present, and future; Detailed explanation of SOAP 1.1; An overview of SOAP 1.2 and XML Protocol; IBM's Web Services Toolkit and Microsoft's SOAP toolkit 2.0; Other SOAP implementations in Perl, C++, and PHP; Java Web Services with Apache SOAP; WSDL 1.1, UDDI 1.0, and 2.0; Creating and deploying Web Services using .Net; Building Web Services using Python; and Applying security at both transport and application levels.

Professional XML Meta Data takes a look at some of the initiatives at the bleeding edge of the XML meta data world. In this book you will see how schemas, topic maps, RDF, and inferencing can be put to use in the field of data description, discovery, and exchange.

Professional XML Schemas exhaustively details the W3C XML Schema language, and teaches the new syntax in an intuitive and logical way. From declaring elements and attributes, creating complex content models and working with multiple namespaces, you'll move on to see how XML Schemas are used in real-world situations. A number of practical case studies will illustrate the design and creation of schemas in the diverse worlds of relational databases, document management, and e-commerce applications.

This column takes a look at how to use XLink pointers when representing data to make XML documents more compact and flexible. Sample code shows examples of an invoice with and without the XLink pointers, plus an example of using XLinks with a URL-addressable database.

This is the first installment of "Working XML", a column with companion project code that demonstrates the evolution of full-fledged XML applications. This column introduces XM (XSLT Make), a simple and affordable Web publishing content-management solution that takes advantage of XML and XSLT. Code samples show the development of a wrapper for the XSLT to make it easy for a nonprogrammer to use. XM project code is available by link.

XLink, an XML-related specification, lets you achieve dramatic linking effects in your XML documents. In this short tip learn how to include parts of other XML documents in your own XML through XLink. The code example demonstrates the technique.

This column demonstrates how to use XML Schema archetyping (and style sheets) to control styling of data for various presentation modes. Ten code samples in XML, XML Schema, and XSLT show how the techniques work to reduce code bulk and simplify maintenance.
