Selecting Input and Output Formats : Understanding Output Formats : XML+XSL
The XML+XSL format generates Extensible Markup Language (XML) data files that are formatted by an Extensible Stylesheet Language (XSL) style sheet.
XML+XSL is recommended to create template rules that output specific data and perform other functions, such as sorting data and outputting data only when certain conditions exist in the XML document. You can also re-purpose the data for different delivery purposes and mechanisms by customizing the base XSL style sheet.For example, through XSL you can deliver XML or HTML to display in a Web browser, or you can deliver text to display on a wireless phone.
