Sorting Tables Using Client Side XSLT [June 29]
Mark House presents a practical use for XML and XSLT, in the guise of lists sort-able on the client side. In doing so the example reduces the processing load on the server, and hands over the rendering of the XML to the client. This can significantly reduce the demands on the network, web server, and database server if you're currently using them to handle display changes. And from a design standpoint, it can also avoid the undesirable (though sometimes necessary) page refresh.

A WML Primer [June 28]
Developers interested in programming for wireless devices such as mobile phones and personal digital assistants must use the Wireless Application Protocol (WAP). To develop WAP applications, Wireless Markup Language (WML), which is based on XML, is designed to display content on mobile devices, much like we use HTML to mark up the content of Web pages. In fact, WML is similar to HTML in that it uses tags and attributes to mark up data and render content on wireless devices. Let's take a more detailed look at some WML elements and short examples that show you how to use them.

An introduction to XQuery [June 27]
A look at the W3C's proposed standard for an XML query language. Howard Katz 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.

Understanding XML Namespaces [June 26]
Namespaces are the source of much confusion in XML, espe-cially for those new to the technology. Most of the questions that I receive from readers, students, and conference attendees are related to namespaces in one way or another. It's actually kind of ironic since the Namespaces in XML Recommendation (http://www.w3.org/TR/REC-xml-names) is one of the shorter XML specifications, coming in at just under 10 pages, excluding appendices. The confusion, however, is related to namespace semantics as opposed to the syntax outlined by the specification. To fully understand XML namespaces, you must know what a namespace is, how namespaces are defined, and how they are used.

Storing XML in Relational Databases [June 21]
There are various ways to solve the problem of effective, automatic conversion of XML data into and out of relational databases. Database vendors such as IBM, Microsoft, Oracle, and Sybase have developed tools to assist in converting XML documents into relational tables. This article explores in detail these vendor's solutions and attempts to answer the questions such as: Can we restructure the and simplify the problem?,; What is the right approach in a heterogeneous database environment?

Web Services: Component Based Application Revolution: a Powerpoint presentation (PPT file) [June 21]
Presented at XML Devcon 2001 NY, powerpoint format. Web Services offers a new model and methodology for building and using applications by integrating components over the web. The emergence of the SOAP, UDDI, and WSDL standards enable the explosive growth of this model, paralleling the growth of the web with the HTML and HTTP standards. This session will discuss the motivation for and importance of Web Services, and the pieces of the puzzle provided by each of the above standards.

Microsoft Windows HTTP Services (WinHTTP) Technology Preview released! [June 18]
WinHTTP provides developers with a server-supported, high-level interface to the HTTP Internet protocol. WinHTTP is designed to be used primarily in server-based applications, such as Microsoft Internet Information Services-based middle-tier servers, to send requests via the HTTP protocol to other servers. WinHTTP offers both a Win32 ‘C’ API set, as well as a COM Automation component suitable for use in Active Server Pages-based applications.
WinHTTP requires either Windows 2000 or later, or Windows NT 4.0 with Microsoft Internet Explorer version 5.01 or later. The version of Internet Explorer can be determined by accessing the “About Internet Explorer” item on the “Help” menu. The version number reported in the About dialog should be 5.00.2900.6300 or higher.
WinHTTP does not support, and will not function correctly on, the Windows 95, Windows 98 and Windows Millennium Edition (ME) platforms, nor does it support Windows NT 4.0 platforms that have versions of Internet Explorer prior to 5.01.

Use XSLT to Merge XML Documents [June 16]
Three types of merge operations using XSLT templates make combining data in separate XML documents simple. XML documents excel at validating, extracting, storing, and transmitting hierarchical data, but as they become more common, the need to merge data stored in different XML documents increases as well. You can use XSLT to merge data from two or more XML documents into a single document, but the process is not as intuitive as it might be.

Build a Reusable Table Viewer: Use XML and XSLT to create a reusable table viewer with client-side paging. [June 11]
Web applications that display data in tabular format and allow users to sort and page through that data can be useful but cumbersome and tedious to implement. You can eliminate the headache of writing similar code over and over by using the client-side capabilities of Extensible Markup Language (XML) and Extensible Stylesheet Language Transformations (XSLT). I'll show you how to let users sort and page without wasting time returning to the server to sort the records or return the next batch. You'll save coding effort and speed development by building a reusable interface for viewing recordset data in tabular format, and you'll meet users' expectations more effectively by providing client-side paging and sorting.

Process and Output Data Queries Using XML: Use XML as a part of your Java development environment to build information pipelines to the client easily [June 08]
Many developers are intrigued by the revolution in data access, movement, and display that XML defines. The value of using XML in this context is that, unlike traditional methods of dynamically generating data-driven pages, it separates the data from its presentation. This means that you can use the same XML document to present data to a variety of different browsers and even clients without writing additional code. The result could be a data-driven application with a browser front end that is both versatile and easy to write and maintain. How does XML provide these benefits? By using separate XSL style sheets, you can take the same XML data and convert it into the appropriate format for the desired browser or client. In this manner, the same XML document can be transformed into HTML for browser-based display, WML for wireless devices, or HDML interactive voice response systems. And rather than requiring additional programming, an HTML writer or Web designer can create the base XML files, inserting database and query information defined by the programmer in the application specification.

Converting Your existing HTML to XML [June 03]
This article will be helpful for sites where a lot of information is maintained as flat HTML pages. All these site's pages share some kind of similar structure and the site developers think that the content should be separated from the publishing elements in order to support rendering media other than a browser or in order to have more control over the rendering itself.
