XML Query

• An introduction to XQuery
  Howard Katz; IBM developerWorks (NEW 02. July)
  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.
• Comparative Analysis of the Most Representative XML Query Languages
  Angela Bonifati (NEW 29. May)
  Part I: Description of XML-GL; Part II: Comparison among the MR XML Query Languages (Lorel, XML-QL, XML-GL, XSL, XQL, Quilt); Part III: More examples... (plus Yatl and XDuce); Part IV: Translators from XML-GL to Lorel, XQL and Quilt; Part V: Active Rules for XML

• The Pros and Cons of XML
  Ronald Schmelzer (NEW 07. August)
  A lot has been written, said, and discussed about the Extensible Markup Language (XML). As a result, there is a lot of confusion and chaos regarding exactly what XML means. Is it a language, document, modeling tool, e-Business application, or none of the above? What exactly does XML have to offer? Why does it matter? Furthermore, what does XML bring to the table that other languages, documents, tools, and applications have not been able to do in myriad other ways?
