What Is XSL?

XSL is a formatting language that applies templating to consistent data repetitions inside XML documents. For example, an XML page containing a listing of clients and their addresses could be formatted into a nice looking table field using an XSL style sheet that showed each different client on a single row in the table, as shown in Figure 1-2.

The HTML equivalent of XSL is cascading style sheets (CSS).
