For those of you that have been following along, PHPBuilder.com has posted the third and final part of their "Using XML: A PHP Developer's Primer" series. Even if you haven't been keeping up, it's worth a look.
In this edition, they look at more advanced topics - a deeper look at Ajax and how to style the data you get back with XSL, both on the client and sever.
To start, they look at XSL - what it is, how it's used, and some code examples of both the XML and XSL structures to style XML data into a valid HTML page. Of course, you'll need the PHP extension to get this all working, so they step you through the installation/enabling of that as well.
