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. This second edition provides: A high-level overview and quick tour of XQuery New chapters on higher-order functions, maps, arrays, and JSON A carefully paced tutorial that teaches XQuery without being bogged down by the details Advanced concepts for taking advantage of modularity, namespaces, typing, and schemas Guidelines for working with specific types of data, such as numbers, strings, dates, URIs, maps and arrays XQuery’s implementation-specific features and its relationship to other standards including SQL and XSLT A complete alphabetical reference to the built-in functions, types, and error messages

“An excellent, early look at the emerging XML Query standard. The chapters on surprises and gotchas alone are worth the price of admission!” —Ashok Malhotra, Architect, Microsoft “XQuery is the most important XML standard to emerge in recent years, and is a language with which anyone using XML on a regular basis should become acquainted. Michael Brundage's accessible introduction to XQuery provides enough information on all aspects of the standard, including its dark corners, to allow any XML developer to jump right in and start coding.” —Damien Fisher, Kernel Team Member, Soda Technologies Pty Ltd “This book does an excellent job of distilling the essentials of XQuery in an understandable, straightforward and easily digestable manner. This book has already become an indispensible part of my library and is a welcome addition to my XML repertoire.” —Dare Obasanjo, Program Manager, Microsoft Corporation “Simply put, the emerging XQuery standard adds enormous value to XML data and this book is your key to unlocking that value. Here in one stop you will find an accessible introduction to XQuery and a complete reference. Practitioners will particularly value the sections on XQuery idioms and surprises where Michael shares his tricks of the trade.” —Dave Van Buren, Project Manager, Jet Propulsion Laboratory “It’s both a stupendous reference on XQuery and a good read. Michael writes with verve, authority, and an eminently readable style. What a rare delight to discover all this, and in a technical book too! When the sequel comes along, sign me up.” —Howard Katz, Owner, Fatdog Software Inc., Editor, XQuery from the Experts (Addison-Wesley, 2003) From corporate IT departments to academic institutions, XML has become the language of choice for storing and transmitting data across diverse application domains. XQuery, an XML Query Language invented by the World Wide Web Consortium, offers a powerful, standardized way to query all of that XML-encapsulated information. With its ability to integrate XML and non-XML data, XQuery seems poised to do for XML what SQL has done for relational data. Written by the Technical Lead for XML query processing at Microsoft, XQuery: The XML Query Language is an invaluable resource for XQuery novices and experts alike. For those new to XQuery, this example-rich text serves as a tutorial that brings readers quickly up to speed on XQuery's data model, type system, and core language features. More experienced XML and database developers will find an excellent reference on the nuances of various expressions, as well as a guide to using XQuery to accomplish specific tasks. Drawing on his experiences using XQuery, Michael Brundage offers an objective, inside look at this emerging technology. His unique perspective translates into an accessible and authoritative guide for readers using XML for documents, Web services, or databases. Key coverage includes: Data model and type system Path navigation Iteration, construction, arithmetic, text processing, type operators and user-defined functions Information beyond the standard—such as a look at update languages, performance benchmarks, query optimization, XQuery style, and much, much more Hundreds of examples The future of XQuery The appendixes provide in-depth information on XQuery's type system, core expressions, built-in functions, regular expressions, and grammar. Meanwhile, the companion Web site offers downloadable source code for all of the examples in the book, the latest on the XQuery standard, answers to readers' questions, XQuery tips and strategies, and more. XQuery will show developers, programmers, and database administrators how a single line of this deep and powerful new language can accomplish the equivalent of hundreds of lines written in C, C#, Java, and other general-purpose programming languages.

XQuery Kick Startdelivers a concise introduction to the XQuery standard, and useful implementation advice for developers needing to put it into practice. The book starts by explaining the role of XQuery in the XML family of specifications, and its relationship with XPath. The authors then explain the specification in detail, describing the semantics and data model, before moving to examples using XQuery to manipulate XML databases and document storage systems. Later chapters discuss Java implementations of XQuery and development tools that facilitate the development of Web sites with XQuery. This book is up to date with the latest XQuery specifications, and includes coverage of new features for extending the XQuery language.

Recently, we have seen a steep increase in the popularity and adoption of XML, in areas such as traditional databases, e-business, the scientific environment, and on the web. Querying XML documents and data efficiently is a challenging issue; this book approaches search on XML data by combining content-based methods from information retrieval and structure-based XML query methods and presents the following parts: applications, query languages, retrieval models, implementing intelligent XML systems, and evaluation. To appreciate the book, basic knowledge of traditional database technology, information retrieval, and XML is needed. The book is ideally suited for courses or seminars at the graduate level as well as for education of research and development professionals working on Web applications, digital libraries, database systems, and information retrieval.

XML has become the lingua franca for representing business data, for exchanging information between business partners and applications, and for adding structure– and sometimes meaning—to text-based documents. XML offers some special challenges and opportunities in the area of search: querying XML can produce very precise, fine-grained results, if you know how to express and execute those queries. For software developers and systems architects: this book teaches the most useful approaches to querying XML documents and repositories. This book will also help managers and project leaders grasp how “querying XML fits into the larger context of querying and XML. Querying XML provides a comprehensive background from fundamental concepts (What is XML?) to data models (the Infoset, PSVI, XQuery Data Model), to APIs (querying XML from SQL or Java) and more. * Presents the concepts clearly, and demonstrates them with illustrations and examples; offers a thorough mastery of the subject area in a single book. * Provides comprehensive coverage of XML query languages, and the concepts needed to understand them completely (such as the XQuery Data Model). * Shows how to query XML documents and data using: XPath (the XML Path Language); XQuery, soon to be the new W3C Recommendation for querying XML; XQuery's companion XQueryX; and SQL, featuring the SQL/XML * Includes an extensive set of XQuery, XPath, SQL, Java, and other examples, with links to downloadable code and data samples.
