Unable to parse SOAP response

Hi Team,

I am very new to Alloy started working on SOAP services using SUDS library. I am able to frame the service and hit the service successfully. But unable to parse the response.

Please help me in this issue.

suds.invoke('TrackRequest', args1,
  function  (xmlDoc) {
      xmlDoc = Titanium.XML.parseString(this.responseText);
        Ti.API.info('Document XML' + xmlDoc);
 
    // Response in console -- Document XML[object TiDOMDocument]
 
    var result = xmlDoc.documentElement.getElementsByTagName("TrackReply");
    Ti.API.info("Response Message!!!!!!" + result);
 
    // Response in console -- Response Message!!!!!![object TiDOMNodeList]
 
    var items = [];
    items= xmlDoc.getElementByTagName("TrackDetails");
    Ti.API.info("     items@@@@@     "     +items);
 
    // Response in console -- items@@@@@     undefined
 
    var data =[];
 
    var elements =[];
    elements = xmlDoc.documentElement.getElementsByTagName("Events");
    Ti.API.info("Events tag %%%%%%" + elements);
 
    // Response in console -- Events tag %%%[object TiDOMNodeList]
