can the Muenchian method do this?

Hi,

I would like to select a distinct value based on a sibling. I know that
the Muenchian method is used to select distinct values, but can I give it
another variable to look at?

Here is my xml:
<songlist>
<song>
<Artist>J-Live</Artist>
<Genre>Rap</Genre>
</song>
<song>
<Artist>Phish</Artist>
<Genre>Rock</Genre>
</song>
<song>
<Artist>J-Live</Artist>
<Genre>Rap</Genre>
</song>
<song>
<Artist>Jay-Z</Artist>
<Genre>Rap</Genre>
</song>
</songlist>

I would like to select all the artists whose Genre is 'Rap' but not have
duplicates. So my return set would be 'J-Live, Jay-Z'

Is this possible? I know I can do this with recursion, but obviously the
Muenchian method is preferred.

Thanks,
Dan
