[xsl] Advice for XSL development

[Pierre-Yves <pingou@xxxxxxxxxxxx>]

Dear list,

I am looking for some help about my xsl.
There are the information from

> Vendor: Transformiix
> Vendor URL: http://www.mozilla.org/projects/xslt/

There is my question:
I would like to transform some XML to div that contains a list.

XML input:
--------------------------------------------------------------
<Simple>
  <OSE>
    <String articleName="Description">some blabla</String>
    <String articleName="Name">test1</String>
    <Integer articleName="Id">681</Integer>
    <String articleName="FactorValue">Value1</String>
  </OSE>
</Simple>
<Simple>
  <OSE>
    <String articleName="Description">some blabla</String>
    <String articleName="Name">test1</String>
    <Integer articleName="Id">682</Integer>
    <String articleName="FactorValue">Value2</String>
  </OSE>
</Simple>
<Simple>
  <OSE>
    <String articleName="Description">some blabla</String>
    <String articleName="Name">test2</String>
    <Integer articleName="Id">683</Integer>
    <String articleName="FactorValue">Value3</String>
  </OSE>
</Simple>
<Simple>
  <OSE>
    <String articleName="Description">some blabla</String>
    <String articleName="Name">test2</String>
    <Integer articleName="Id">684</Integer>
    <String articleName="FactorValue">Value4</String>
  </OSE>
</Simple>
--------------------------------------------------
Basically I would like to transform that to:
<table>

  <tr onclick="dosomething('test1')">
    <td>test1</td>
    <td>some blabla</td>
  </tr>
  <tr>
	<td>
	  <table id="test1">
		<tr>
	    	<td>Value1</td>
	    	<td>681</td>
		</tr>
		<tr>
    		<td>Value2</td>
    		<td>682</td>
		</tr>
	  </table>
	</td>
  </tr>

  <tr onclick="dosomething('test2')">
    <td>test2</td>
    <td>some blabla</td>
  </tr>
  <tr>
	<td>
	  <table id="test2">
		<tr>
	    	<td>Value3</td>
	    	<td>683</td>
		</tr>
		<tr>
    		<td>Value4</td>
    		<td>684</td>
		</tr>
	  </table>
	</td>
  </tr>

</table>
------------------------------------------------------

I know how to fit the String element but I am not sure how I can group 
the element by Name to generate the table.

Has anyone ever done something like this ?

Thanks in advance for your help,

Best regards,

Pierre
