I have the following code 

<xsl:result-document href="output1/output3/index.html" format="html">
 <html>
 <head>
<SCRIPT LANGUAGE="JavaScript">
function getParams() 
{
var idx = document.URL.indexOf('?');
var params = new Array();
if (idx != -1) {
var pairs = document.URL.substring(idx+1, document.URL.length).split('&amp;');
for (var i=0; i&lt;pairs.length; i++) {
nameVal = pairs[i].split('=');
params[nameVal[0]] = nameVal[1];
   }
}
return params;
}
params = getParams();
</SCRIPT>

<SCRIPT LANGUAGE="JavaScript">
val = unescape(params["value"]);
document.write("value = " + val);
</SCRIPT>
</head>

<body>
 <xsl:choose>
    <xsl:when test="a:id=''">
    <xsl:value-of select="a:name"/>
    </xsl:when>
 </xsl:choose>
</body>
</html>
</xsl:result-document>

i want to access the javascript variable ‘val’ in xsl:when’. I need the value so that I can run the condition. Any ideas – How to do it?

    Saxon-CE is an XSLT 2.0 processor that runs in the browser. It’s compiled to JavaScript and provides a high level of JavaScript interoperability. JavaScript/DOM nodes, numbers, strings, boolean values and arrays (converted to XSLT 2.0 sequences) work relatively seamlessly across the JavaScript/XSLT interface.

    For your specific case you have various options in Saxon-CE; you can directly call an existing or injected JavaScript function using ixsl:call() or you can use ixsl:get() to retrieve the value of a variable. Or, you can do the whole thing from within your XSLT 2.0:

    Here’s the same code included as text instead of a graphic – without formatting

    <xsl:transform
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:ixsl="http://saxonica.com/ns/interactiveXSLT"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"

    version="2.0"

    <xsl:template match="/">
        <xsl:variable name="urlparams" select="ixsl:get(
            ixsl:get(ixsl:window(),'location'),
            'search')"
            as="xs:string"/>
        <xsl:variable name ="pairs" select="tokenize(substring($urlparams,2), '&amp;')"
            as="xs:string*"/>
        <xsl:variable name="value" select="f:getValue($pairs)"/>
        <p>value: <xsl:value-of select="$value"/></p>
        
        <xsl:choose>
            <xsl:when test="a:id eq $value">
                <xsl:value-of select="a:name"/>
            </xsl:when>
        </xsl:choose>
    
    </xsl:template>
    
    <xsl:function name="f:getValue" as="xs:string*">

        <xsl:sequence select="for $p in $pairs,
           $v in substring-before($p, '=')
        return
            if ($v eq 'value')
                then substring($p, string-length($v) + 2)
            else ()"/>
    </xsl:function>
