grouping and counting of data using xslt

[jermine]

Im new with xml stuff, and i was hoping some of the gurus here can put me in the right direction. I tried the key generate-id thing but cant seem to make it work.

here's my problem :
I want to display the following data in a tabular format and count the data based on their grouping.


My data :

 <data>
  <feesOwed>
    <Year>2005</Year>
    <LastName>Hallett</LastName>
    <Chapter>NY</Chapter>
    <Amount>25</Amount>
  </feesOwed>
  <feesOwed>
    <Year>2005</Year>
    <LastName>Vincent</LastName>
     <Chapter>TX</Chapter>
    <Amount>25</Amount>
  </feesOwed>
  <feesOwed>
    <Year>2005</Year>
    <LastName>Macoleni</LastName>
      <Chapter>NY</Chapter>
    <Amount>40</Amount>
  </feesOwed>
  <feesOwed>
    <Year>2004</Year>
    <LastName>Strauss</LastName>
      <Chapter>PA</Chapter>
    <Amount>10</Amount>
  </feesOwed>
 </data>

Desired output is :

Year Chapter LastName Amount
2004 PA Strauss 10
2005 NY Vincent 25
(space) (space) Hallett 25
(space) (space) Macoleni 40


AND having totals between each chapter and year.
Is this possible? or am i reaching for the stars already?

thanks in advance!
