Professional XML, The Book

I had a chance to work with a great team on the new edition of Professional XML. This is a completely new edition; everything is fresh and has be written from the ground up. The book covers almost all the XML-related technologies you can think of: XSLT, XPath, XML Schema, Relax NG, XSL-FO, XHTML, XQuery, Ajax, RSS, Atom, Web services, and many others. For the XPath chapter, instead of writing a 30-page overview of XPath, I decided to take a different approach: looking at a number of specific features of XPath that are both very useful in practice, and somehow lesser known or not obvious. I have already alluded to some in this very blog:

• Debugging with trace()
• Reverse Axis, Evil at Times
• The unordered() function, Quite an Oddity
• Tuning your XPath Expressions
• The Many Faces of a Document
• When A != B is different from not(A = B)

Grab a copy of the book, and you will find more about XPath, and of course much more about a number of other XML technologies. I hope you will enjoy it!
