The most effective way to use XML in your site is with Dreamweaver's XSLT server behavior. It processes all of those "X" files and produces nothing but clean HTML for your visitors. To take advantage of this feature, you'll need to set up an application server, as described in Chapter 20, so that you can run ASP, PHP, JSP, .NET, or ColdFusion pages with the necessary programming code.
Next, you need to either have an XML file in your site, or know the URL of an XML file out on the Web that you'd like to use—for example, http://www.nationalexasperator.com/news.xml. Then you create an XSLT style sheet—either by creating a new, blank XSLT style sheet or by converting an already created HTML file into a XSL file, as explained starting on Section 24.2.
