XML to HTML - possible?

[Peter Morris]

Newbie-ish question:

I've done a little programming with XML. I can use a cascading
style sheet to specify text format, such things as font, size and style.
But I want something a bit more complex than this.

For example, I want to put a title bar at the top of each page
in my website. Rather than specify the HTML in every page, I'd like
each page to include a piece of XML like this :
<XML ID=TOP>
<PAGE_TITLE> Welcome</PAGE_TITLE>
</XML>
Then use a stylesheet to specify the HTML for this.

A bit more complex: I'd like to read rows from a database table,
returning them as XML, then use a stylesheet to put them in
an HTML table.

Is this even possible?
Any web pages with guides to doing this?

You have to use XSL, here is one fo the website that has XSL tutorial
http://www.w3schools.com. Or do a google search for XSL/XSLT.
