XQuery has earned a reputation for being for one of the mostcautiously developed and, therefore, slowest evolving W3C standards. Akey reason is that there is little industry experience in the retrieval ofinformation stored in XML. Many companies are still innovating in thisfield and are generating a good deal of empirical information that has [...]

XQuery is a rich and expressive language. I love exploring the types of questions you can pose using it. In fact, I enjoy exploring the types of queries you can pose almost as much as I enjoy discovering what those queries can discover (if you can parse that sentiment). I realized around Academy Awards time [...]
Last month I promised to eventually discuss the use of schemas with XSLT 2.0 — that is, XSLT 2.0’s ability to read a W3C schema to discover additional information about a source tree, result tree, or interim temporary tree, and to use that information when processing a document. This month I’ll talk about the use [...]

It led to an open forum on, as described in the agenda, "how to achieve hassle free news exchange". The goal of the meeting was, according to the summit [...]
XSL and Cascading Style Sheets (CSS) have similar goals, and it’s useful to compare them. XSL is more powerful than CSS in many ways, but it’s also more complex. XSL and CSS are not competitors. For some common applications (like HTML+ documents that [...]

In the last article I describeda new model for web services construction. It is called Representational StateTransfer (REST), and it applies the principles of the Web totransaction-oriented services, rather than publishing-oriented sites. When weapply the strategy in the real world, we do so using web technologies such asURIs, HTTP, and XML. Unlike the current generation [...]
Xerox’s Raven is a prototype of an XML editor developed as a research project within one of Xerox’s technical publications departments. The design objective is to target the low end of the editing spectrum with a tool that is simple to install and maintain, supports forms-based data entry, and is effective in a distributed authoring [...]
This is the last article in our series on Voice XML, so let’s wrapthings up by expanding your thinking about how you can use voice as an enablerfor your applications. When we look at the classic success stories of Voice XML(for example, the American Airlines flight service or 1.800.DOMINOS), we seeVoice XML as a front [...]
