Over from the phpTraveller this morning, there's their own review of the new Wrox book, Professional PHP4 XML.

Although I do not like big books (never have enough time to read them thoroughly), I had a "just right" feeling from the moment I picked this one. As I said above, this is probably due to the fact that you can pick one subtechnology at a time and not feel overwhelmed with the rest. [...] This book's biggest problem is the insufficient space dedicated to SOAP. As much as I do not like it (SOAP), there is a large force in the industry behind it and we have to work with it. However, it is quite likely (haven't read it yet) that another Wrox book, Professional PHP Services, covers SOAP in depth. That makes it up for its lack of coverage here.

Sounds like the folks at Wrox have another PHP winner on their hands, this time with XML as the focus. Of course, I personally haven't been let down by a Wrox purchase yet, so here's hoping *crosses fingers*...
