Reading variable data from XML file

Here is a video from Adobe on using XML in Captivate:

Common JavaScript Interface in Adobe Captivate 8 - YouTube

They had the project from the YouTube video available for download in the past but I can't find it now.

Here is how I interpreted the video to use it on Entering a slide. I populate the 6 book variables with the XML data:

var myBookArray = new Object();

xmlhttp=new XMLHttpRequest();

xmlhttp.open("GET","Assurance.xml",false);

xmlhttp.send();

xmlDoc=xmlhttp.responseXML;

var a=xmlDoc.getElementsByTagName("proBook");

for (i=0;i<a.length;i++)

  {

  var at = a.attributes;

  myBookArray[i+1] = a.childNodes[0].nodeValue;

  }

window.cpAPIInterface.setVariableValue("book1", window.myBookArray[1]);

window.cpAPIInterface.setVariableValue("book2", window.myBookArray[2]);

window.cpAPIInterface.setVariableValue("book3", window.myBookArray[3]);

window.cpAPIInterface.setVariableValue("book4", window.myBookArray[4]);

window.cpAPIInterface.setVariableValue("book5", window.myBookArray[5]);

window.cpAPIInterface.setVariableValue("book6", window.myBookArray[6]);
