xsltProcessor to set a variable

I need to use xsltProcessor to set a variable to something.

What xsltProcessor function would I use  -  the below does not work.

Code:


var item = document.getElementById("descriptionInput");

xmlDoc = myXMLHTTPRequest.responseXML;
            var search = xsltProcessor.transformToFragment(xmlDoc, document);
            
            myDOM = search;
            
            document.getElementById("XMLDiv").innerHTML = search;


I want to make search an xsltprocessor variable with value of item.

Is this possible?

Please help im so close to finishing this.

Thank you
John
