Below my .sig is an XSLT stylesheet that will do the trick. Save it to 
your filesystem as, e.g., comps.xsl. Then use xsltproc to apply it to 
the comps.xml file, e.g.,

   xsltproc --novalid comps.xsl /path/to/repodata/comps.xml > comps.html

The resulting HTML file will provide you a reasonable list of packages 
associated with each group.

Warning: the list might not be complete because any given package in 
your named group(s) might might require packages not in those groups. 
That's why anaconda does dependency checking at installation time.
