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
