A very very good book. chapters are well divided into smaller chunks, well sequenced.

Priscilla Walmsley (who was a member of the W3C XML Schema Working Group and I believe the XQuery Working Group as well) is an excellent writer and teacher.

It has a very clear introduction, which gets you going and the rest of the chapters are sufficiently detailed to be useful.

I've had this XQuery book for about a week now and it has already helped me immensely! Priscilla Walmsley (who was a member of the W3C XML Schema Working Group and I believe the XQuery Working Group as well) is an excellent writer and teacher. Her writing style is clear and concise, as anyone who read her earlier Definitive XML Schema book already knows.

"XQuery" is roughly 2/3 tutorial and 1/3 reference (by page counts). The tutorial material is thoughtfully divided into 25 bite-size chapters. The topics progress nicely from an overview and basics to important concepts such as namespace handlng, modules and static typing. The book includes 5 chapters that focus on handling specific data types (e.g, "Working with Strings"). You don't have to know XSLT but knowing XPath may be helpful. OTOH, XPath is covered in Chap. 4. There is even a chapter targeted at SQL users. I also appreciate the carefully chosen running example that is representative of many XML structures. The book also benefits from special icons indicating tips, gotchas, and compatibility issues. Longtime XML geek Simon St.Laurent was the O'Reilly editor, which is another big plus.

Walmsley has also created an incredibly useful reference site of XQuery functions, both those defined by the W3C specs and numerous others that she wrote. Others may contribute as well. [...]

I have several older XQuery books by various publishers but this book is by far the best. I highly recommend it to web developers, database developers, and data architects with even a modest XML background.

Format: Paperback
The use of XML has become ubiquitous over the last five years, and thus a huge amount of data is now stored in XML, both as databases and as documents. XML data can include highly structured data such as sales figures, less structured data such as product catalogs, and unstructured data such as books. With such a variety of data stored as XML, in each case different elements of the data must be formatted and transformed in a particular way. This is where XQuery comes in. It is a query language that allows the user to select those XML data elements of interest, reorganize them, transform them, and finally return the results in a data structure. This book acts as an up-to-date tutorial and reference on this useful technology. There are plenty of examples shown that illustrate the concepts being presented. The following is a detailed description of the book's contents:

1. Introduction to XQuery - Provides the basic purpose and capabilities of XQuery and also acts as a quick introduction to its features. It provides a basic familiarity with the most commonly used kinds of expressions, without getting too bogged down in the details.

2. XQuery Foundations - a brief overview of the foundations of XQuery including its design, its place among XML-related standards, and its processing model. It also discusses the underlying data model behind XQuery and the use of types and namespaces in queries.

3. Expressions: XQuery Building Blocks - The basic unit of evaluation in XQuery is the expression. A query contains expressions that can be made up of a number of sub-expressions, which may themselves be composed from other sub-expressions.

My first impression of this book is that it is fantastic. Just flip through the first chapter and you'll see references to code snippets and valuable explanations of XQuery. This book is what I was seeking. The author knows the reader has an interest in the subject and does not waste time explaining what XML is and why one would want to query it etc. This book is not selling the technology. It teaches it which is a lesson the author of "Querying XML" could learn from.

I am very happy thus far with this book.

I needed to come up to speed with an XML database server (Mark Logic) and I found this book very useful for learning how to use XQuery. It was concise and provided many good examples. The presentation of chapters was somewhat episodic--you had to read the later chapters to find out how some of the topics turned out. This was probably due to the newness and complexity of the topic. I wouldn't be surprised if there was a chapter reorg for the 2nd edition.

In my case, the book covers only XQuery and does not cover the XQuery extensions and specifics of the XML database system I was using. Walmsley's book makes a great companion to the vendor documentation.

XML programmers and database users will find Priscilla Walmsley's XQUERY a specific, valuable reference which is based on the Xquery 1.0 standards and which offers a basic tutorial on specifications and programming with the query language base. Query writers should have some knowledge of XML basics to use this, and can quickly progress into the 'advanced' category using an overview and tour of Xquery which includes guidelines for working with different types of data and an A-Z reference to the program's functions.

This is a nice, comprehensive book written by someone highly qualified to talk about XQuery. The author, Priscilla Walmsley, was a member of the W3C XML Schema Working Group.

Now that XML is being added to database management systems, DBAs and database developers will need to know how to query that data. And they'll more than likely be using XQuery to do it. As such, this book would be a good way for database professionals to gain expertise on XQuery.

Walmsley's book offers a concise, yet in-depth tutorial on the XQuery language specification. After digesting these 25 chapters you'll have the knowledge required to program using XQuery to read your XML data. Whether you're coming from a relational and SQL background or you're an XML and XSLT coder, this well-written text will help you understand and write queries using XQuery.
