The W3C XQuery 3.1 standard provides a tool to search, extract, and manipulate content, whether it's in XML, JSON or plain text. With this fully updated, in-depth tutorial, you’ll learn to program with this highly practical query language. Designed for query writers who have some knowledge of XML basics, but not necessarily advanced knowledge of XML-related technologies, this book is ideal as both a tutorial and a reference. You’ll find background information for namespaces, schemas, built-in types, and regular expressions that are relevant to writing XML queries.

With the XQuery 1.0 standard, you finally have a tool that will make it much easier to search, extract and manipulate information from XML content stored in databases. This in-depth tutorial not only walks you through the XQuery specification, but also teaches you how to program with this widely anticipated query language. XQuery is for query writers who have some knowledge of XML basics, but not necessarily advanced knowledge of XML-related technologies. It can be used both as a tutorial, by reading cover to cover, and as a reference, by using the comprehensive index and appendixes. Either way, you will find the background knowledge in namespaces, schemas, built-in types and regular expressions that is relevant to writing XML queries. This book provides: A high-level overview and quick tour of XQuery Information to write sophisticated queries, without being bogged down by the details of types, namespaces, and schemas Advanced concepts for users who want to take advantage of modularity, namespaces, typing and schemas Guidelines for working with specific types of data, such as numbers, strings, dates, URIs and processing instructions A complete alphabetical reference to the built-in functions and types You will also learn about XQuery's support for filtering, sorting, and grouping data, as well as how to use FLWOR expressions, XPath, and XQuery tools for extracting and combining information. With this book, you will discover how to apply all of these tools to a wide variety of data sources, and how to recombine information from multiple sources into a single final output result. Whether you're coming from SQL, XSLT, or starting from scratch, this carefully paced tutorial takes you through the final 1.0 standard in detail.

Co-authors are the world-renowned inventor of markup languages and a developer of the W3C XML Schema specification Detailed coverage of Office 2003 Professional XML features, plus all the XML knowledge you need to use them Learn to edit your XML document with Word, analyze its data with Excel, store it with Access, and publish it to the Web with FrontPage® Build dynamic custom XML forms with the remarkable new InfoPath™ 2003—structured data collection with word processing flexibility From the Foreword by Jean Paoli, Microsoft XML Architect and co-editor of the W3C XML specification: “XML enabled the transfer of information from server to server and server to client, even in cross-platform environments. But the desktop, where documents are created and analyzed by millions of information workers, could not easily participate. Business-critical information was locked inside data storage systems or individual documents, forcing companies to adopt inefficient and duplicative business processes. “This is a book on re-inventing the way millions of people write and interact with documents. It succeeds in communicating the novel underlying vision of Office 2003 XML while focusing on task-oriented, hands-on skills for using the product.” Desktop XML affects every Office 2003 Professional Edition user! It transforms millions of desktop computers from mere word processors into rich clients for Web services, editing front-ends for XML content management systems, and portals for XML-based application integration. And this book shows you how to benefit from it. You’ll learn exactly what XML can do for you, and you’ll master its key concepts, all in the context of the Office products you already know and use. With 200 tested and working code and markup examples and over 150 screenshots and illustrations from the actual shipped product (not betas), you’ll see step by step how: Office users can share documents more easily, without error-prone rework, re-keying, or cut-and-paste. Office data from your documents can be captured for enterprise databases. Office documents can be kept up-to-date with live data from Web Services and enterprise data stores. Office solutions can overcome traditional limitations by using XML and Smart Documents. BONUS XML SKILLS SECTION!
