Google Docs and Xpath Data Functions
In this tutorial, we will teach you how to use Xpath data functions (such as ImportXML) to retrieve information from Google Docs and other outside sources.

Flex Array Collection Sort and Filtering
It's not unusual to need to write an application that can filter and sort a list of items based on user input. Maybe your e-commerce shop offers a variety of notebooks from different companies, and you want visitors to be able to sort or filter your selection. Combining Flex with ActionScript allows you to create such an application with a minimum amount of hassle (and code), as you'll see in this article.

The Flex Tree Control
The Flex Tree control is amazingly useful when building applications, especially if you're dealing with hierarchical data. To learn how to add the power of this intuitive organizational component to your developer's toolbox, keep reading.

Flex List Controls
The List Control is a fundamental control for use in Flex. It can be used in many different situations and can display all types of data. Anything from images to plain text and even basic HTML (supported by Flex) can be used. Keep reading for an introduction to this versatile control.

Working with Flex and Datagrids
Flex 3.0 offers a strong foundation of user interface (UI) controls by which users can harness a great deal of power to create beautiful UIs without having to toil in the details of low level functionality. Of these controls, the DataGrid sets itself apart by offering characteristics similar to a list or tree control (which are also listBase controls), but going further to offer an easy way of displaying columnar data without a complicated interface. In this article, I focus on creating a basic DataGrid and populating it with XML data by using only MXML tags.

How to Set Up Podcasting and Vodcasting
There are various forms of web syndication available to web site owners. The syndicated distribution of media is known as Podcasting. In this article we will focus on delivering different audio and video (sometimes called Vodcasting) media to your subscribers.

Creating an RSS Reader Application
In the previous two articles we discussed how to read and build an RSS document with PHP. In this article we will create an application that uses the concepts discussed in the other two articles. So letís go straight to the coding.

Building an RSS File
In the previous article we discussed how to read an RSS file with PHP. In this article we will focus on the theoretical aspects of how to build an RSS file.

An Introduction to XUL Part 6
Learn about XUL, a subset of XML used to describe user interfaces, that helps you to make rich user interfaces with nothing more complicated than a text editor. In the sixth part of this series learn about XBL, another of XMLís many faces and a partner in crime with XUL, also called XML Binding Language.

An Introduction to XUL Part 5
Learn about XUL, a subset of XML used to describe user interfaces, that helps you to make rich user interfaces with nothing more complicated than a text editor. In the fifth part of this series you will receive an introduction to XPCOM, the object model used by XUL, and take a close look at a basic example of the combination of Mozilla components and interfaces that make up the abstraction layer.

An Introduction to XUL Part 4
Learn about XUL, a subset of XML used to describe user interfaces, that helps you to make rich user interfaces with nothing more complicated than a text editor. In the fourth part of this series you will learn about dialog boxes and wizards.

An Introduction to XUL Part 3
Learn about XUL, a subset of XML used to describe user interfaces, that helps you to make rich user interfaces with nothing more complicated than a text editor. In the third part of this series covers layout and content elements.

An Introduction to XUL Part 2
Learn about XUL, a subset of XML used to describe user interfaces, that helps you to make rich user interfaces with nothing more complicated than a text editor. In the second part of this series, Dan Wellman covers implementing more kinds of buttons. He also begins talking about creating Menu Bars, Tooltips, and Status Bars.

An Introduction to XUL Part 1
Would you like to learn how to make rich user interfaces with nothing more complicated than a text editor? Welcome to XUL, a subset of XML used to describe user interfaces. This article will get you started.

XML Matters: Practical XML Data Design and Manipulation for Voting Systems
EVM2003 brings XML to the democratic process. In this installment, David discusses his practical experiences developing interrelated XML data formats for the EVM2003 Free Software project to develop voting machines that produce voter-verifiable paper ballots. Some design principles of format subsetting emerge. In addition, David looks at how an application-specific meaning for XML document equivalence can be programmed, and why canonicalization is insufficient. (This intermediate-level article was first published by IBM developerWorks, June 28, 2004, at http://www.ibm.com/developerWorks.)

Practical XML Data Design and Manipulation for Voting Systems
EVM2003 brings XML to the democratic process: In this article, David Mertz discusses his practical experiences developing interrelated XML data formats for the EVM2003 Free Software project to develop voting machines that produce voter-verifiable paper ballots. Some design principles of format subsetting emerge. In addition, David looks at how an application-specific meaning for XML document equivalence can be programmed, and why canonicalization is insufficient.

SimpleXML
Learn an easy way to parse XML and output it the way you want by using the simpleXML extensions in PHP5. Murray outlines the 3 main elements of an XML document and how to replace them with your own non-template data and how to build an array of all the tags put in the document.

XForms Basics, Part 3
In the previous article, I showed you how to manage user input in the XForms model. I discussed the process of submitting an XForm and Ė more importantly - validating user input prior to submission using built-in XML Schema support. In this concluding article, find out how to use the lt;xforms:bind gt; element to perform calculations on form input values, integrate XPath expressions into your XForms model and get a crash course in the XForms event model.

XForms Basics, Part 2
In the first part of this series, I gave you a quick introduction to the newly-released XForms 1.0 specification, by explaining the fundamental concepts of the XForms model. Now that you know the basics, find out how to submit XForms data to a server-side script or save it to a local client file, and also read about how XForms can integrate with XML Schemas to simplify input validation.

XForms Basics
Today, XML is most definitely in the mainstream, and proving its mettle by making all kinds of new and unique applications possible (witness the success of Amazon.com's AWS service, or the Google APIs, both based on XML technology). This article provides an introduction to XForms, a recent W3C Recommendation that suggests using XML to manage the display, input and processing of form data on the Web.
