hello there,

I did get help from here earlier on
creating an index from my report xml-file.
Now I would need some more help on the matter.

My xml-file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<raport>
<tables>
<table number="1">
<section gen="0" type="PARE">
<person> <name><givenname>Lars </givenname><surname>Schalin</surname></name>
<notices>
<notice tag="BIRT">Syntynyt <date value="17540101">01.01.1754</date>
<place name="Hanebo">Hanebo</place>. </notice>
<notice tag="DEAT">Kuollut <date value="18081010">10.10.1808</date>
<place name="Vaasa">Vaasa</place>. </notice>
</notices>
</person>
</section>
.............

<section gen="1" type="PARE"><person>
.....
</person>
</section>
</table>
</tables>
</raport>


I am now trying to create a place index from this data.
place elements are located inside table elements and it is possible
that there are more than one place index in the same table.
e.g. person was born and he died in the same place.

In the place index I want each table number where it is found only once.
I have succeeded with the xslt-file below to create a place index but I have
not succeeded
to remove the double table references.

I assume it should be done by grouping using the muenchian method the same
way as I grouped the places as I have tried here. Can anybody help me with
this?
