How to extract data from RDF written in many different ways

I'm using XSLT to present data from RDF documents to users and run into some
problems because of the ambiguous nature of RDF. Below is an example
document of RDF that has the same thing, i.e. I'm the creator of this
document, expressed in few possible ways. What I'm trying to solve here is
how to manage the different tree structures that my stylesheet might have to
handle.

I would like to gain access to the actual value elements so that I could use
them in a template to format the data. The values are (see example RDF in
the end):

[1] "Jarno Elovirta"
[2] "Jarno Elovirta"
[3] "Jarno Elovirta"
[4] "Jarno Elovirta"
[5] "<vc:N rdf:parseType="Resource">
       <vc:Family>Elovirta</vc:Family>
       <vc:Given>Jarno</vc:Given>
     </vc:N>"
[4] "Jarno Elovirta"
[5] "<vc:N rdf:parseType="Resource">
       <vc:Family>Elovirta</vc:Family>
       <vc:Given>Jarno</vc:Given>
     </vc:N>"

Also the qualifier element values (if they exist) need to be used in that
stylesheet.

My first problems arose with the need to define the ordering of multiple
occurrences of the same Dublin Core element. Also the fact that I want to
use a template for the value presented some problems (don't ask me how, I
tried about a million stylesheets). All of this would not be difficult to do
if I just wrote a template to handle all the possibilities, but Dublin Core
has 15 fields and we use our own fields, too, so writing templates for all
possibilities would be... not that good of an idea. So, if there's anyone
willing to share their stylesheets on this problem, I'd be grateful. And if
there's a simple solution to this I missed, you can publicly shave my legs
and call me grandpa!
