商品描述
The W3C XQuery 3.1 standard provides a tool to search, extract, and manipulate information from XML content. With this fully updated, in-depth tutorial, you’ll not only learn how to use the XQuery specification, but also how 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.
Organized into six parts, this book includes:
- 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
