Working XML: Safe coding practices, Part 1
Benoit reviewed his project notes and has compiled a list of the most common pitfalls with XML technology. Save yourself a great deal of frustration by watching out for these potential problems in your own projects. In the first article in this series of four, Benoit reviews the hazards of the XML language itself.

Working XML: Building a compiler for the SAX ContentHandler
This installment of the column describes the requirements for the Java project and analyzes its overall design. The new project, called HC (short for Handler Compiler), will take some drudgery out of event-based XML parsing by automatically generating the SAX ContentHandler for a list of XPaths.

Working XML: The Eclipse task list
After more than a year, Benoit returns to the XM (XSLT Make) project. He reports on changes with the Eclipse platform and embarks on a major update that will integrate XM more tightly with Eclipse. As a starting point, he looks into a simple interface enhancement that is often requested: support for the problem and task lists or, more specifically, support for markers. As you will see, working with these lists requires an indirection. He also looks into Eclipse's own resource management and discusses techniques for writing code that works equally well from within Eclipse and from the command line.

Working XML: A lightweight XML client
While excellent solutions are available for large corporations that want to implement XML, few solutions exist for smaller organizations. In this article, Benoit Marchal launches a new project for the Working XML column: an XML client for e-commerce, born out of his experience with B2B e-commerce over the last couple of years. Share your thoughts on this article with the author and other readers in the accompanying discussion forum.

Working XML: Fundamentals of Web publishing with XML
As more developers learn and experiment with XML, many have become interested in using stylesheets to publish and manage Web sites. But getting started is not always that easy. Although none of the concepts, taken in isolation, is difficult, putting them together coherently is not a trivial undertaking. In this article, Benoit Marchal provides step-by-step instructions to get you started. He shows how to organize your project in source, rules (stylesheets), and publishing directories. You'll also get some practical tips on XML editors.

Working XML: Integrating XM and Eclipse
The more author and columnist Benoît Marchal learns about Eclipse and the plug-in API, the more he likes what he sees. In this column, Benoît continues his ongoing project to integrate XM (a simple content management and publishing solution based on XML and XSLT) and Eclipse (an open-source project to define a next-generation Integrated Development Environment for Java developers). His effort pays off when XM launches from the IDE. As a bonus, Benoît finds a basic XML editor already hidden in the toolkit!

Working XML: Putting XI to good use
When it comes to user interfaces, simplification is the key. Fewer options and fewer controls mean less confusion and less chance for error. The author uses the concept of less is more to create a user interface that makes XI, the text-to-XML conversion tool, easier to use and more palatable.

Working XML: Wrapping up XI
Columnist Benoit Marchal continues to shape XI, an open-source project that converts legacy text to XML. For increased efficiency, XI now implements the SAX XMLReader interface, which proves handy in linking XI to an XSLT processor. Code samples demonstrate the techniques, and the complete source code is available as well. Each month the column reports on the author's open source projects designed to assist fellow XML developers, especially those working with Java technology.

Working XML: Define and load extension points
In this article, Benoit takes integration between XM, the simple content-management solution, and Eclipse one step further. Publishing a Web site requires you to work with many file types in addition to XML, so it makes sense to design a publishing system around an extensible core. Eclipse plug-ins fit the bill nicely. Benoit shows how to make the XM plug-in extensible to accommodate multiple file types.

Index of XML standards
The world of XML is vast and growing, with a huge variety of standards and technologies that interact in complex ways. It can be difficult for beginners to navigate the most important aspects of XML, and for users to keep track of new entries and changes in the space. XML is a basic syntax upon which you develop local and global vocabularies. This index provides a detailed cross-reference of many XML standards, including links to additional coverage for each.
