If you've been working with XML, or maybe just want to get started in the XML world (it's not just a buzzword anymore), then this book review might interest you.

This piece, "XML for the World Wide Web is a sound guide to the basics", covers the PeachPit Press book about XML and its place on the internet. It covers such things as XML standards, DTDs, schemas, XSLT (yay!), CSS and XML, and, of course, XPath/XPointer.

Of course, it's not without its problems: XML for The World Wide Web is best suited for a beginner with basic knowledge of HTML or for a developer who needs to cut to the chase and understand XML quickly. It doesn't cover more advanced XML concepts, such as SOAP, Simple API for XML (SAX), or Document Object Model (DOM). It also doesn't show you how to integrate XML with other languages, such as Java.

So, learn the XML, use the XML, then dive right into the PHP XML functionality...
