Description

This training 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
Participants 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. During the training they will find out 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.
