Most people think of XQuery as a query language for processing XML "databases". But it is also a very nice language for generating XML and HTML, including web pages. In this article we will look at XQuery from this angle.

Howard Katz introduces the W3C's XQuery specification, currently winding its way toward Recommendation status. The complex specification currently consists of 12 separate working drafts (and may still be growing). 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 Query Language will soon become the "SQL for XML." Be prepared for the next version of Microsoft SQL Server by using a preview of the Microsoft.Xml.XQuery classes.

XML blurs the distinctions between databases, documents, and messages, but it needs a powerful and elegant query language to reach its full potential. XPath does not go far enough. XQuery intends to be that language.

Query may cause one of the biggest changes to server-side programming since Java servlets. XQuery is a query language specification under development by the World Wide Web Consortium (W3C) that's designed to query collections of XML data—not just XML files, but anything that can appear as XML, including relational databases.

The eXtensible Markup Language (XML) started its life as replacement for the immens popularly but limited HTML-format. In time, it became apparent that XML was even more useful "outside the browser" and that it was extremely suitable as a format for data interchange and data storage. The popularity and wide-spread use of XML has led to a large and continuously growing amount of XML documents and a strong demand for efficient storage, query and retrieval solutions.

In this installment of Practical XQuery I continue to discuss practical uses of XQuery, focusing this time on interactive web page generation. The sample application will display a list of books; based on user input, it will also display detailed information about the selected title.

The XQuery/XSLT working group released another set of Working Drafts on August 22, 2003. This article is my attempt to summarize the significant changes in the new drafts. Note that there is no new version of either the Data Model or Functions and Operators specifications, which were released to Last Call in May.

In this article we will show to to write and install a very simple web application written in the XQuery language. We will also show you how errors are handled, and how you can debug them. Our application uses the servlet extension of Qexo (version 1.7beta2 or later), a free software implementation of XQuery.
