I have scoured through numerous posts that try and explain how to achieve this, however none have helped me solve the problem.
I have a HTML file which contains an XML parsing JavaScript function which in turn renders the XSLT file. The issue is, I have multiple 'records' in my XML file and I only want a single XSLT to render each of records (instead of a separate XSLT file per record). Based on the code below, please could someone advise on how I can pass a parameter from JavaScript containing the record id (in each XML record in my XML file) so that the 'single' XSLT can parse the layout with the correct data sourced from the parameter.

Reset to default 5In the XSLT you need to change
<xsl:template match="/">
<!-- How do I use the value of the parameter sent via JavaScript for the cityname (in place of value 'London') -->
<xsl:for-each select="locations/location[cityname='London']">
to
<xsl:param name="cityname"/>
<xsl:template match="/">
<!-- How do I use the value of the parameter sent via JavaScript for the cityname (in place of value 'London') -->
<xsl:for-each select="locations/location[cityname = $cityname]">
I would also set <xsl:output method="html"/> as you are only creating a fragment of HTML and the XSLT processor does not know that if you don't set the output method.
In your Javascript code for Mozilla, Chrome, Opera I would change the check
else if (document.implementation && document.implementation.createDocument) {
xsltProcessor = new XSLTProcessor();
xsltProcessor.importStylesheet(xslt);
/** I believe this is how to set the param, but it didn't work **/
//xsltProcessor.setParameter(null, "cityname", currentLocation);
resultDocument = xsltProcessor.transformToFragment(xml, document);
document.getElementById("WeatherDetailsContainer").appendChild(resultDocument);
}
to
else if (typeof XSLTProcessor !== 'undefined') {
var xsltProcessor = new XSLTProcessor();
xsltProcessor.importStylesheet(xslt);
xsltProcessor.setParameter(null, "cityname", currentLocation);
var resultFragment = xsltProcessor.transformToFragment(xml, document);
document.getElementById("WeatherDetailsContainer").appendChild(resultFragment);
}
Your IE code with transformNode does not allow to set parameters, you will need to change that part as well, change
if (window.ActiveXObject || xhttp.responseType == "msxml-document") {
ex = xml.transformNode(xslt);
document.getElementById("WeatherDetailsContainer").innerHTML = ex;
}
to
if (window.ActiveXObject || xhttp.responseType == "msxml-document") {
var template = new ActiveXObject('Msxml2.XslTemplate');
template.stylesheet = xslt;
var proc = template.createProcessor();
proc.input = xml;
proc.addParameter('cityname', currentLocation);
proc.transform();
document.getElementById("WeatherDetailsContainer").innerHTML = proc.output;
}
It looks like you had the right code in your Javascript for passing in the parameter, but your XSLT has to also be written to accept the parameter:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3/1999/XSL/Transform">
<!-- Declare it here -->
<xsl:param name="cityName" />
<xsl:template match="/">
<!-- use it here ------v -->
<xsl:for-each select="locations/location[cityname = $cityName]">
...
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
