You need to use Exhibit 2.0 for this. Be warned, Exhibit 2.0 is still in active development and should not be considered stable yet (release date predicted circa late September).

Simply edit the link rel="exhibit/data" elements to point to the RDF-XML data you want to pull in, and exhibit does the rest.
