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

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.

This book covers in a great depth the fast growing topic of techniques, tools and applications of soft computing in XML data management. It is shown how XML data management (like model, query, integration) can be covered with a soft computing focus. This book aims to provide a single account of current studies in soft computing approaches to XML data management. The objective of the book is to provide the state of the art information to researchers, practitioners, and graduate students of the Web intelligence, and at the same time serving the information technology professional faced with non-traditional applications that make the application of conventional approaches difficult or impossible.

As more developers use XML to store and define in their applications, they need tools to process and manipulate it. XQuery is the official World Wide Web Consortium (W3C) specification for an XML query language. The final version of XQuery is expected at the end of 2002, and developers will crave information and useful implementation advice about this new XML tool. XQuery Kick Start will deliver both - covering the full specification and providing useful examples for developers to put into practice immediately. The book starts by explaining the role of XQuery in the XML family of specifications, and its very direct relationship to XPath. The authors then explain the specification in detail, describing the semantics and data model, before moving to examples of XQuery's use in manipulating XML databases and document storage systems. Later chapters discuss the .NET and Java implementations of XQuery and discuss development tools that facilitate XQuery development.

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.

Referring to specific information inside an XML document is a little like finding a needle in a haystack: how do you differentiate the information you need from everything else? XPath and XPointer are two closely related languages that play a key role in XML processing by allowing developers to find these needles and manipulate embedded information. XPath describes a route for finding specific items by defining a path through the hierarchy of an XML document, abstracting only the information that's relevant for identifying the data. XPointer extends XPath to identify more complex parts of documents. The two technologies are critical for developers seeking needles in haystacks in various types of processing.XPath and XPointer fills an essential need for XML developers by focusing directly on a critical topic that has been covered only briefly. Written by John Simpson, an author with considerable XML experience, the book offers practical knowledge of the two languages that underpin XML, XSLT and XLink. XPath and XPointer cuts through basic theory and provides real-world examples that you can use right away.Written for XML and XSLT developers and anyone else who needs to address information in XML documents, the book assumes a working knowledge of XML and XSLT. It begins with an introduction to XPath basics. You'll learn about location steps and paths, XPath functions and numeric operators. Once you've covered XPath in depth, you'll move on to XPointer--its background, syntax, and forms of addressing. By the time you've finished the book, you'll know how to construct a full XPointer (one that uses an XPath location path to address document content) and completely understand both the XPath and XPointer features it uses.XPath and XPointer contains material on the forthcoming XPath 2.0 spec and EXSLT extensions, as well as versions 1.0 of both XPath and XPointer. A succinct but thorough hands-on guide, no other book on the market provides comprehensive information on these two key XML technologies in one place.
