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 gain 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 XQueryInformation to write sophisticated queries, without being bogged down by the details of types, namespaces, and schemasAdvanced concepts for users who want to take advantage of modularity, namespaces, typing, and schemasGuidelines for working with specific types of data, such as numbers, strings, dates, URIs, and processing instructionsA complete alphabetical reference to the built-in functions and typesYou will also learn about XQuerys support for filtering, sorting, and grouping data, as well as how to use FLWOR expressions, XPath, and XQuery tools for extracting and combining information.
