I have an XML file containing data which I need to access in the  
controller. For example, the XML file contains cpu usage and cpu load  
and other such information. I need to collect this information into a  
controller and display it in a graph (chartdirector). How do I get the  
values from the XML file to the controller?

Open the file and use Nokogiri (gem) to parse the XML.

Did you checkout the nokogiri plugin? Also there is ReXML

Where would you recommend putting all of the parsing code, in a Model  
or Controller? I’m very new at working with MVC, but to be it seems  
that an XML document, being a representation of data, would be handled  
by a Model. Am I wrong? Thanks!

You are completely correct, put the reading and parsing in a model  
that is not derived from AR::base
