Another difference between HTML and XML is that unlike HTML, XML provides no formatting information. In HTML, the tag name discloses its format. For example, you expect text within an H1 tag to be larger than text within an H2 tag. XML, on the other hand, has no notation of format whatsoever. You need to use XSL (Extensible Stylesheet Language) or XSLT (XSL Transformation) to display XML information on the Web. XML and XSLT constitute a dynamic and flexible system for handling data and presentation.
