Title: Okay, but look to Wrox's PHP Book
Review: This book contains all the fundamental information you'd expect from a book detailing PHP and XML, however this book fails to cover anything extremely indepth. If you are looking for a more in-depth and technical resource as well as coverage of the latest standards, turn to the Professional PHP4 XML book published by Wrox. That one is much better even though it's a little more money.
