[xsl] Grouping by attribute values

Subject: [xsl] Grouping by attribute values

I have the following problem. My XML is structured in the following way:

<?xml version="1.0" encoding="UTF-8"?>
<ratePremiums rateDate="20041001" territory="100" type="1">
<coverage id="Liability">
<premium class="1" drivingRecord="0" limit="200">820.7014415999998</premium>
<premium class="1" drivingRecord="0" limit="300">853.5294992639998</premium>
<premium class="1" drivingRecord="1" limit="200">805.7559679999999</premium>
<premium class="1" drivingRecord="1" limit="300">837.9862067199999</premium>
<premium class="12" drivingRecord="2" limit="200">0.0</premium>
<premium class="12" drivingRecord="2" limit="300">0.0</premium>

I need to display premiums grouped first by class, then by driving record and then by limit in
HTML tables.

So a table for each class, a row for each driving record and a column for each limit (much like an engineering table).

To elaborate: Desired output for the snipet above is:
Class 1:
<tr><th></th><th>200 K</th><th>300 K</th></tr>
<tr><td>DR = 0</td><td>820.7014415999998</td><td>853.5294992639998</td></tr>
<tr><td>DR = 0</td><td>805.7559679999999</td><td>837.9862067199999</td></tr>
.... etc.

I have no idea how to loop through the premiums, isolated a unique class to create a table. Then for that class loop through unique driving record values and display the premiums according to limit.

I do not want to structure my XML with this table view in mind.

Thank you for your time!
