I'd recommend the book to anyone who'd like a convenient all-in-one-place reference to XML-related technologies and how PHP interacts with them. The book enables a developer to not just pick a tool because it's available, but to make intelligent decisions about which tool is best for their purposes.
It also gives one enough of a head start that understanding much deeper and more technical information on the web or in other books (XSLT Programmers Reference 2nd Edition, Pro PHP4, etc...) becomes easier to digest.
At IBM, we have always been a strong advocator of PHP for being the perfect language for connecting to databases over the web and offering dynamic content and services. It's simple, elegant, easy and effective. Even further, IBM has always explored XML within PHP and has advocated the use of PHP with our DB2 product.
This book takes your existing PHP skills in HTML and databases and brings them to a whole new level. By taking your current knowledge and adding XML into the mix, this book will truely help you think creatively and create more complex applications. Even given all the hype around "Web Services", this book takes an incredible look into XML-RPC and SOAP. The authors have done, in my opinion, a fantastic job.
I give this book 5 stars because it truely deserves such a rating. The book is absolutely solid. If you want to learn anything from the fundamentals of XML all the way to Web Services, this book will show you the path and everything in-between.
The SAX chapter is very interesting read because it goes beyond the installation of the SAX libraries and learning how to use the functions. Covering Expat, the chapter explains a great deal about how to use the less uncommon functions like xml_set_notation_decl_handler(), xml_set_external_entity_ref_handler() and the others effectively. Also of note, the diagrams and code examples were very clear and well done in this chapter. The chapter also looks at writing a properly modeled object-oriented SAX parser using eXtremePHP and covers common problems like removing whitespace, handling erroneous XML input and extending the white box infrastructure within eXtremePHP to create very powerful, yet elegant, XML Parsers.The DOM chapter covers the latest DOM extensions introduced in PHP 4.2.1 and even provides code examples and heads up information on what is to come in PHP 4.3.0. The chapter introduces what DOM is and even shows the reader a beautiful diagram illustrating how all the functions relate to an example. By simply looking at this, you can get a feel for how to use DOM almost immediately. The chapter continues to discuss how to enable DOM within your PHP installation on both Windows and UNIX and looks at the real-world advantages and disadvantages to using DOM over SAX. Next, the chapter explains the new DOM object model and looks at the underlying architecture before diving into any code examples. This information sets up the rest of the chapter, making it a lot easier for non-object oriented programs to visualize what methods belong to what objects and understanding the data relationships of the DOM tree. The chapter then presents a lot of code examples. First, it illustrates how many of the methods and functions of the DOM library work and then covers more complicated examples, illustrating how to parse, create and modify DOM documents with and without using HTML forms. The chapter closes with a pretty comprehensive look into the limitations of the DOM standard, explaining to the reader what the boundaries are, common problems with the API yet unfixed and provides future directions the library might take to correct many of the architectural, standards-based and object-oriented capabilities within the library.
Kudos to everyone that made this book happen.

This is a problem, but with it, I still could recommend this book for everybody not familiar with Web Services, and would like to learn all the related technologies. As it is true at other books, too: you can learn all these things from the web, but you can just find these together in this (or other) book, and you can read it conveniently at your bed with your girlfriend. :)
This is *the* book on the subject. Check it out today.
