This is a great place to start.

Basically, Style Sheets (similar to CSS) can be used on XML documents (by using XSL aka "Style Sheets for XML") to display them in a "HTML Look and Feel".

It's done this way so that there is a clean separation between the content of a HTML page (which is provided as XML) and the actual view/display of it in the users' browser.

This way, different XSL Style Sheets can be used on the same content (i.e. XML).

For example to display the XML in a iPhone or on a desktop monitor there can be two XSL's, one for iPhone and one for the desktop monitor.

Take a look at the following resource for XSL and XSLT:

From the tutorial:

XSL = Style Sheets for XML

XML does not use predefined tags (we can use any tag-names we like), and therefore the meaning of each tag is not well understood.

A tag could mean an HTML table, a piece of furniture, or something else - and a browser does not know how to display it.

XSL describes how the XML document should be displayed!
