Unexpected character in query string in msxml4.dll

I copie the code I found in the smartbear community. Everytime I execute the keywordtest and then i run the function  "getInformationData()", so i could retrieve warning /error count and the time it took to execute the test.

Error message:

Unexpected character in query string.

Nodes/Node[@na--><--me="root"]/Prp[@name="warning count"]/@value

Here is the code JScript :

function getInformationData()
{
  //var tempFolder = aqEnvironment.GetEnvironmentVariable("temp") + "\\" + Math.floor(Math.random() * 10000) + "\\";
  var tempFolder = aqEnvironment.GetEnvironmentVariable("temp") + "\\testXML\\";

  aqFileSystem.CreateFolder(tempFolder);

  Log.SaveResultsAs(tempFolder, lsXML);

  var xDoc = Sys.OleObject("MSXML2.DOMDocument.4.0");

  xDoc.load(tempFolder + "Description.tcLog");
  Log.Message(xDoc.xml);

  // Warning count
  var wrnC = VarToInteger(xDoc.selectSingleNode('Nodes/Node[@na​me="root"]/Prp[@name="warning count"]/@value').text);
  //var wrnC = VarToInteger(xDoc.selectSingleNode('Nodes/Node[@na​me="root"]/Prp[@name="warning test count"]/@value').text);

  //Error count

  var errC = VarToInteger(xDoc.selectSingleNode('Nodes/Node[@na​me="root"]/Prp[@name="error count"]/@value').text);
  //var errC = VarToInteger(xDoc.selectSingleNode('Nodes/Node[@na​me="root"]/Prp[@name="error test count"]/@value').text);

  //Execution time

  var startTime = VarToFloat(xDoc.selectSingleNode('Nodes/Node[@name​="root"]/Prp[@name="start time"]/@value').text);

  var stopTime = VarToFloat(xDoc.selectSingleNode('Nodes/Node[@name​="root"]/Prp[@name="stop time"]/@value').text);
  aqFileSystem.DeleteFolder(tempFolder, true);

  var res =

    "Errors: " + errC + "\r\n" +

    "Warnings: " + wrnC + "\r\n" +

    "Start Time: " + DateTimeToStr(startTime) + "\r\n" +

    "Stop Time: " + DateTimeToStr(stopTime) + "\r\n" +

    "Run Time: " + aqConvert.DateTimeToFormatStr(stopTime - startTime, "%H:%M:%S");

  Log.Message(res);
  //return res;
