This Tutorial Shows the Use of CSS with XML in Flash
By Mindy McAdams, author of Flash Journalism: How to Create Multimedia News Packages
This is an example of how to use CSS together with an XML file to style text in Flash. The template in Flash will read the line breaks herein.

This is a new paragraph, for example.

All the formatting you see in the SWF is controlled by an external CSS style sheet that is using the XML tags to determine the appearance of each element within this XML file. There are some regular HTML tags being used also, but most of the formatting is tied to custom tags in the XML.

Thanks to Neil Webb for his tutorial, which served as the basis for this one.
