Subject: [xsl] Multiple select listbox as parameter

Hi all. I could really use some help...

My XML looks like this:<?xml version='1.0'?>
<Data>
    <Indicator KEY='001'>
          <Group Key='001'/>
          <Group Key='005/>
    </Indicator>
    <Indicator KEY='002'>
         <Group KEY='003'/>
         <Group KEY='002'/>
    </Indicator>
    <Indicator KEY='003'>
         <Group KEY='004'/>
         <Group KEY='003'/>
    </Indicator>
</Data>

I have a list box, where you can select multiple Groups.  If I select
groups 002 and 001, it should return Indicators 001 and 002.  The
paramater that I pass is 001,002,.  So from my XSL, I tried two things.
First was to see if the parameter contained the key:

<xsl:for-each select="Indicator">
<xsl:when test="contains($lstGroup,Group/@KEY)">
 ...do something...
</xsl:when>
<xsl:for-each>

This worked great, but only if the first group matched the criteria.
So it returns just indicator 001.

Then I tried this:

<xsl:for-each select="Indicator">
<xsl:when test="Group[@KEY=$lstGroup]">
 ...do something...
</xsl:when>
<xsl:for-each>

And this works great, except it will not accept a multiple list from
the list box.  Only when I pass one choice to the paramater.

I tried this:

<xsl:for-each select="Indicator">
<xsl:when test="contains($lstGroup,Group[@KEY])">
 ...do something...
</xsl:when>
<xsl:for-each>

But this returned all indicators.

Is there a way to combine the two working bits of code to do what I
want to do?  It may be in the way I call the parameter, or it may be in
the output code.  Here's how I call the parameter from a multiselect
list box:

(This is on my HTML page)
var as Values = New Array();
var oSel = document.sel.lstGroup;
var strGroup1 = ""
for (var i-0; i<oSel.length;i++)[
    if (oSel.options[i].selected){
         asValues[asValues.length]=oSel.options[i].value;
         strGroup1=strGroup1 + oSel.options[i].value + ",";
    }

}


xslproc.addparameter("lstGroup",strGroup1,"");

This passes '001,002,' to my xsl page.

Here is the full version of all of the code.

I also noticed since I put it up, that it's unbearably slow.  Any
suggestions for that?

Any help is greatly appreciated.
Thanks,

You should pass a nodelist to the addParameter method.
Something like:
**********GetGroups.xml************
<Data>
<Indicator KEY='001'>
<Group KEY='001'/>
<Group KEY='005'/>
</Indicator>
<Indicator KEY='002'>
<Group KEY='003'/>
<Group KEY='002'/>
</Indicator>
<Indicator KEY='003'>
<Group KEY='004'/>
<Group KEY='003'/>
</Indicator>
</Data>

******************************
***********GetGroups1.xslt*******
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="lstGroup"/>
<xsl:template match="/Data">
<Indicators>
<xsl:apply-templates select="Indicator[Group/@KEY = $lstGroup]"/>
</Indicators>
</xsl:template>
<xsl:template match="Indicator">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet>
******************************
var _oFTDom = null;
function getSyncFTDom()

if(!_oFTDom)
{
_oFTDom = new ActiveXObject("Msxml2.FreeThreadedDomDocument.4.0");

}
var _oDom = null;
function getSyncDom()
{
if(!_oDom)
{
_oDom = new ActiveXObject("Msxml2.DomDocument.4.0");
}
return _oDom.cloneNode(false);
}

var _oFTTemplate = null;
function getFTTemplate()
{
if (!_oFTTemplate)
{
_oFTTemplate = new ActiveXObject("Msxml2.XSLTemplate.4.0");
}
return _oFTTemplate;
}
function main()
{
var oSource = getSyncDom();
oSource.load("GetGroups.xml");
var oStyle = getSyncFTDom();
oStyle.load("GetGroups1.xslt");
var oTemplate = getFTTemplate();
oTemplate.stylesheet = oStyle;
var oProc = oTemplate.createProcessor();
oProc.input = oSource;
var arrGroupKeys = ["001", "002"];
var oParams = getSyncDom();
oParams.loadXML("<KEYS/>");
for (var i = 0; i < arrGroupKeys.length; i++)
{
(oParams.documentElement.appendChild(oParams.createElement("KEY"))).text = arrGroupKeys[i];
}
oProc.addParameter("lstGroup", oParams.documentElement.selectNodes("KEY"));
oProc.transform();
alert(oProc.output);
}
main();
