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.

Xselerator is a fully functional XSL/XSLT IDE and Debugger. Features: Full stepping capability; Breakpoints on both XSLT and input XML; Conditional breakpoints; View template call stack; Watch values (including full XPath expression watches); Clear and easy to use IDE; XSL/XSLT element and attribute intuitive (like Intellisense or code insight) drop-downs; Automatic tag completion - in XSL/XSLT tag completion follows model and, optionally, fills element with mandatory attributes; HTML element and attribute intuitive drop-downs; Full XSL, XSLT, XML and HTML color syntax highlighting (fully customizable); and All the usual editor capabilities (cut, copy, paste, find, replace) plus special 'Copy as RTF' and 'Copy as HTML' features allowing syntax highlighting to be preserved when copying and pasting to word-processors, html editors and newsgroups etc.

Ever want to know how to bridge processing of an HTML element over two XSLT templates? Here's why not to do it. This article demonstrates how to shift your thinking into the XSLT recursive approach, which is especially helpful if you have a background in a procedural language (Java and the like). Sample code demonstrates the right way (and the wrong way) to work with a flat XML or XHTML file that you want to process hierarchically.

This XML guide explains XML uses, categories, elements and types of XML documents. XML structure, document type definition, element attributes, and extensible stylesheet language (XSL) is explained.

This article presents a practical exploration of knowledge management with XML by illustrating techniques for populating Resource Description Framework (RDF) models with data from existing XML formats. As shown in the three code listings, RDF can be used as a companion to customized XML, not just as a canonical representation for certain types of data. This column, with code samples included, demonstrates how easy it can be to jump-start knowledge management with RDF even relatively late in the development game.

This introductory article shows how to create XML Document Type Definitions (DTDs) and well-formed, well-defined XML files that can be validated by the XML parser of your choice. While you don't have to include a DTD with every XML file you produce, doing so will make your life a lot easier. Not only will a DTD enforce the syntax you've established for your XML files, it will also allow your files to be parsed by a validating XML parser. Code samples include DTD and XML document examples.

This article introduces the W3C's XQuery specification, currently winding its way toward Recommendation status after emerging from a long incubation period behind closed doors. The complex specification consists of six separate working drafts, with more to come. This article provides some background history, a road map into the documentation, and an overview of some of the technical issues involved in the specification. A sidebar takes a quick look at some key features of XQuery's surface syntax. Code samples demonstrate the difference between XQuery and XQueryX and show examples of the surface syntax.

XML Schema Quality Checker is a program which takes as input an XML Schema written in the W3C XML schema language and diagnoses improper uses of the schema language. Where the appropriate action to correct the schema is not obvious, the diagnostic message may include a suggestion about how to make the fix. For Schemas which are composed of numerous schema documents connected via <include> <import> or <redefine> element information items, a full schema-wide checking is performed. The tool can also be run in batch mode to quality check multiple XML schemas in a single run.

The IBM XML Registry/Repository (XRR) is a data management system that manages and provides services for XML artifacts including schemes (DTD, XSD), stylesheets (XSL) and instance documents (WSDL). User can use XRR to obtain an XML artifact automatically, search or browse for an XML artifact, deposit an XML artifact with or without related data, and register an XML artifact without deposit.

XSLbyDemo is a technology for generating XSLT rules on the basis of editing operations conducted under on the WYSIWYG view of an HTML editor. XSLbyDemo is available for full-fledged HTML editors, namely, IBM WebSphere Studio Page Designer (v3.5 or greater), and IBM WebSphere Homepage Builder (v.6.0.3 or greater).

This article casts a critical eye on the Simple Object Access Protocol, assessing the value this much-discussed new technology can provide developers and demonstrating its foundation in a mixture of the old RPC (remote procedure calls) technology and in XML. It examines RPC, XML-RPC, RMI, and SOAP in detail, comparing and contrasting the use of each, and discusses whether SOAP makes sense. This article also includes sample code for a SOAP envelope.

This article demonstrates how to automate e-mail publishing chores with Java and XML. This concrete application of XML and XSLT describes an e-mail newsletter (e-zine) publishing application that outputs both HTML and plain text e-mail messages. Five reusable code samples include a Java program to send e-mails using JavaMail, an XSLT style sheet to convert the DocBook sample introduced in Part 1 to HTML, a Java configuration handler (in the form of a SAX ContentHandler), and the Java code that puts it all together in a multistepped transformation.
