How to make the user selecting a view in a XSL stylesheet from a button


Hi,
I am using XML through IE 5 with MSXML3.0.

I have this XML document:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<?xml:stylesheet type="text/xsl" href="select_advise.xsl" ?>
<LIST_ADVISE>
<LIST_SUBJECT>
	<SUBJECT>Blé tendre</SUBJECT>
	<SUBJECT>Graines de colza</SUBJECT>
	<SUBJECT>Graines de tournesol</SUBJECT>
	<SUBJECT>Maïs</SUBJECT>
	<SUBJECT>Orge de mouture</SUBJECT>
	<SUBJECT>Pois</SUBJECT>
</LIST_SUBJECT>

<ADVISE ID="133">
	<DATE>2000-08-03</DATE>
	<CATEGORIE>Céréales</CATEGORIE>
	<SUJET>Blé tendre</SUJET>
	<COMMENT>comment </COMMENT>
</ADVISE>

<ADVISE ID="135">
	<DATE>2000-08-03</DATE>
	<CATEGORIE>Céréales</CATEGORIE>
	<SUJET>Maïs</SUJET>
	<COMMENT>comment</COMMENT>
</ADVISE>
<ADVISE...
...
</ADVISE>
...
</LIST_ADVISE>

I want to propose the user to select what advise he wants to see by
selecting the subject in a list and then clicking on a button. I know how to
construct the select option.
I don't find how to pass the parameter to a xsl variable and to re-process
the xml document.

Does anybody have an  idea ?

Here's my xsl document (or parts of it)

-> select_advise.xsl
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:user="mynamespace"
version="1.0">
<xsl:output method="html" version="4.0"/>

<msxsl:script language="JScript" implements-prefix="user">
<![CDATA[     
var CATS ="ABC";
    function ok(e) {
	//THIS CALL DON'T WORK IN A button
	// IT WORKS ONLY IN THIS CASE:  <xsl:value-of select="user:ok(.)"/>
	// I DONT FIND HOW TO USE IT WITH A BUTTON
	return  "1";
    }
  ]]> 
</msxsl:script>

   <xsl:template match="/">
               <xsl:apply-templates select="LISTE_ADVISE" />
   </xsl:template>


<xsl:template match="LISTE_ADVISE">
	<H1>Conseils</H1>
	<form name="formulaire">
	<table CELLPADDING="5" CELLSPACING="0" border="1" bordercolor="#A8D000" >
	<tr>
	<td>
	<table CELLPADDING="0" CELLSPACING="0" width="650">
	<tr>
	<td>Selectionner un grain</td>
	<td>	<select name="grain" id="grain">
	        <option value=""></option>
		<xsl:apply-templates select="LISTE_SUBJECT/*" />
		</select></td></tr>
	<tr><td colspan="2">
		<input type="button" onclick="ok(document.forms[0])" value="Submit" />
	</td></tr>
	</table>
	</td></tr></table>
	</form>

	<table CELLPADDING="5" CELLSPACING="0" border="1" bordercolor="#A8D000" >
	<tr>
	<td>
		...
		<xsl:apply-templates select="ADVISE" >
		<xsl:sort order="descending" select="DATE"/>
		<xsl:sort select="SUJET"/>
		</xsl:apply-templates>
		....
	</td>
	</tr>
	</table>
</xsl:template>      

<xsl:template match="SUBJECT">
	<OPTION value="{.}"> <xsl:value-of select="." /></OPTION>
</xsl:template>	  

<xsl:template match="CONSEIL">
	<xsl:value-of select="SUJET"/> ...
	<xsl:value-of select="COMMENTAIRE"/>
</xsl:template>
</xsl:stylesheet>
  
Thanks.

Stéphane Mamdy.
