Authoritative: Priscilla Walmsley is a W3C insider and author of the best-selling book "Definitive XML Schema". This book provides complete coverage of the W3C XQuery 1.0 standard. XQuery 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. XQuery and its related specifications are more than 1,000 printed pages. This book condenses that information and explains it in plain English.;A new survey of developers using XML has found that a vast majority are using or plan to use XQuery even before it becomes a standard because of the language's ability to simplify data extraction. DataDirect Technologies Inc. surveyed 550 developers on their plans for XQuery usage, and 52 percent said they are already using it, while 33 percent said they plan to use it this year. - eWeek.com There readers can find all the examples, as well as any errata.
