Parsers vs. processors ???

As a newbie, I'd like some help getting all the functions straight. 

What are all the inputs to the XML parsers? What are all the outputs?

What are all the inputs to the XSL processor? What are all the outputs?

This will help me with the BIG PICTURE and set me up for my next questions
about XSLT and XPath.

Thanks for any enlightenment.
