O'Reilly Releases "XQuery"
Search Across a Variety of XML Data

Sebastopol, CA--In recent years the use of XML has grown explosively; as a
result, an enormous amount of information is now stored in XML, both in
XML databases and in documents on a filesystem. This includes highly
structured data, such as sales figures, semi-structured data such as
product catalogs and yellow pages, and relatively unstructured data, such
as letters and books. And even more information is passed between systems
as transitory XML documents. 

XQuery 1.0 is the tool that makes it easier to search, extract, and
manipulate this information. The query language, designed by the W3C,
allows you to select the XML data elements of interest, reorganize and
possibly transform them, and return the results in a structure of your
choosing. According to Priscilla Walmsley, author of "XQuery" (O'Reilly,
US $49.99), "there are as many reasons to query XML as there are reasons
to use XML." 

A few examples of common uses for the XQuery language are:

-Extracting information from a relational database for use in a web
service
-Generating reports on data stored in a database for presentation on the
web as HTML
-Searching textual documents in a native XML database and presenting the
results
-Pulling data from databases or packaged software and transforming it for
application integration

"XQuery" was written for query writers who have some knowledge of XML
basics but not necessarily advanced knowledge of XML-related technologies.
It can be used as a tutorial, by reading it cover-to-cover, and as a
reference, by using the comprehensive index and appendixes. 

The book provides complete coverage of the XQuery 1.0 standard that was
finalized in January 2007. In addition, it provides the background
knowledge in namespaces, schemas, built-in types, and regular expressions
relevant to writing XML queries.  Contents include:

-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

Whether you're coming from SQL, XSLT, or starting from scratch, this
carefully paced tutorial takes you through the final 1.0 standards in
detail.
