XQuery
With the XQuery 1.0 standard, you finally have a tool that
will make it much easier to search, extract and manipulate
information from XML content stored in databases. This
in-depth tutorial not only walks you through the XQuery
specification, but also teaches you how to program with this
widely anticipated query language.
XQuery
is for query writers who have some knowledge of XML
basics, but not necessarily advanced knowledge of
XML-related technologies. 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
find 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 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
You 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. With this book, you will discover 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.
Whether you're coming from SQL, XSLT, or starting from
scratch, this carefully paced tutorial takes you through the
final 1.0 standard in detail.
