XML/XSL transformation and DocumentFragment resultant parsing

[Thomas Griffith]

Hello. Thank you for reading my question. I am returning XML from a Tomcat servlet and transforming with XSL. i am converting this from MSXML to XHR. For whatever reason, if I feed in the source XML, evaluate does it's thing. However, if I transform XML using the stylesheet and the resultant is a DocumentFragment (doc_trans...set to resultDoc, the JS code evaluates to the "else"...alert("no"). I want to use an evaluate on the resultant document to determine how the number of <tr>. selectNodes allows this in MSXML..

Maybe need to convert the DocumentFragment before running evaluate? But to what? Thank you so much.

doc_trans=xsltProcessor.transformToFragment(doc_xml_source, document);

//var resultDoc=doc_xnl_source;
var resultDoc=doc_trans;

//var path = "/catalog/cd/title"
path="/html/body/table//row";

if (resultDoc.evaluate) {
    alert("yes");
    var nodes = resultDoc.evaluate(path, resultDoc, null, XPathResult.ANY_TYPE, null);
    var result = nodes.iterateNext();
    while (result) {
    alert(result.childNodes[0].nodeValue);
        txt += result.childNodes[0].nodeValue + "<br>";
        result = nodes.iterateNext();
    } 
    } else {
 alert("no");


//Approach 1....Try to parse for <tr> via an XpathEvaluator....
var evaluator = new XPathEvaluator();

//DocumentFragment not a valid node type exception thrown here...

var resulty = evaluator.evaluate("//tbody/tr", resultDoc, null, 
XPathResult.ORDERED_NODE_SNAPSHOT_TYPE);

alert( resulty.snapshotLength);  


//Approach 2...Try to convert DocumentFragment to an HTML element...

var html_element=document.createElement("div2");
html_element.appendChild(resultDoc);

var evaluator = new XPathEvaluator();

//TypeError: Cannot read property 'snapshotLength' of undefined is thrown here...
var result = evaluator.evaluate("//tbody/tr", html_element, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE);
