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.","brand":"WoB","offers":[{"title":"GB \/ GOOD \/ INTERNAL","offer_id":49652961050897,"sku":"GOR004226946","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50186187637009,"sku":"GOR006638009","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":50357888319761,"sku":"CIN0596006349G","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0596006349.jpg?v=1750699211"},{"product_id":"definitive-xml-schema-book-priscilla-walmsley-9780132886727","title":"Definitive XML Schema","description":"“XML Schema 1.1 has gone from strong data typing to positively stalwart—so powerful it can enforce database level constraints and business rules, so your data transfer code won’t have to. This book covers the 1.1 changes—and more—in its 500 revisions to Priscilla Walmsley’s 10-year best-selling classic. It’s the guide you need to navigate XML Schema’s complexity—and master its power!”   —Charles F. Goldfarb       For Ten Years the World’s Favorite Guide to XML Schema—Now Extensively Revised for Version 1.1 and Today’s Best Practices!       To leverage XML’s full power, organizations need shared vocabularies based on XML Schema. For a full decade, Definitive XML Schema has been the most practical, accessible, and usable guide to working with XML Schema. Now, author Priscilla Walmsley has thoroughly updated her classic to fully reflect XML Schema 1.1, and to present new best practices for designing successful schemas.       Priscilla helped create XML Schema as a member of the W3C XML Schema Working Group, so she is well qualified to explain the W3C recommendation with insight and clarity. Her book teaches practical techniques for writing schemas to support any application, including many new use cases. You’ll discover how XML Schema 1.1 provides a rigorous, complete specification for modeling XML document structure, content, and datatypes; and walk through the many aspects of designing and applying schemas, including composition, instance validation, documentation, and namespaces. Then, building on the fundamentals, Priscilla introduces powerful advanced techniques ranging from type derivation to identity constraints.
