XML schedule!!

[kenny_oh]

i got one assignment question but i not really understand...can anyone explain to me and i'm new to XML..

Qs:
create a DTD to define an XML language that can represent a television schedule. using your XML language definition, create an example XML file for a schedule. Create an XSLT file and a CSS file that can render your XML into XHTML suitable for display in a web browser. Create a web page to demonstrate your XSLT in action using either server side or client side XSLT rendering

You're asking quite a lot there
The best thing you can do, to help you answer the latter assignments too, is go to this site: http://www.w3schools.com/
Check the links on the left to see how to use XML, DTDs and XSLT
