Hi,

I'm new to XSL and have been given an assignment which has me stumed.
I'm hoping you could assist. I've been given a set of XML data (see
format below) and have been asked to produce a normalized bar grap in
html for output.

<xml>
  <rs:data>
   <z:row class='book' title='nice book' status='open' />
   <z:row class='book' title='good book' status='closed' />
   <z:row class='book' title='aweful book' status='closed' />
   <z:row class='vase' title='blue vase' status='open' />
   <z:row class='vase' title='red vase' status='closed' />
   <z:row class='vase' title='green vase' status='open' />
  </rs:data>
</xml>

The idea would be to have for each data row grouped per class and the
relative number of statuses computed.

Based on the above input the expected output would be as follows.

<table>
  <tr><th>class</th><th span=2>graph</th></tr>
  <tr><td>book</th><td width='33%'>open<td><td width='67%'>closed<td></
tr>
  <tr><td>vase</th><td width='33%'>open<td><td width='67%'>closed<td></
tr>
</table>

It should be noted that the number of different values the status
attribute can take can vary (ie. it can be more than just open an
closed as in the example above).

If you feel writing up XSL for this is trivial then your help would be
greatly appreciated.
