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
