Because XML provides flexible document-definition and processing capabilities, it lets you reformat data for multiple devices and platforms.

Because XML separates display instruction from content definition, Web designers can alter their Web Site's look and feel by using the Extensible Stylesheet Language [XSL] documents to apply different style sheets to the same XML document.

This then allows you to use the same content for devices such as Personal digital assistants or PDAs and wireless devices that do not use HTML for display processing.

XML allows online information search and retrieval to be fast and efficient.
