  • 0

I am new to XML coding and I am working on a site right now to help me improve on the skill. I think i got all the syntax right for the page but it seems not to be working. Here’s the code for the index page and also the xml file I am trying to make use of. 

<html>
<body>

<script type="text/javascript">
var link= "http://api.remix.bestbuy.com/v1/stores(area(55423,10))+products(name=playstation*)?show=storeId,name,products.sku,products.name&page=1&apiKey=ydpyq9h9cmpmzaakbawv9mzk";
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.open("GET","test.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML; 
document.write("<table border='1'>");
var x = xmlDoc.getElementsByTagName("name");
for (i=0;i<5;i++)
  { 
  document.write("<tr><td>"); 
  document.write(x[i].getElementsByTagName("name")[0].childNodes[0].nodeValue);
   document.write("Step 2");
  document.write("</td><td>");
  document.write(x[i].getElementsByTagName("distance")[0].childNodes[0].nodeValue);
  document.write("</td></tr>");
  }
document.write("</table>");
</script>

</body>
</html>

and the XML i got off a sample best buy request

    You will have to put the code that executes after the data is loaded in the onreadystatechange event of the xmlhttp object: http://www.w3schools.com/ajax/ajax_xmlhttprequest_onreadystatechange.asp

    xmlhttp.onreadystatechange = function() {
    if (httprequest.readyState == 4) {
        // Response finished
        if (httprequest.status = 200) {
           // everything OK
           // Parse the data
        } else {
           // Something gone wrong with the request
        }
    }
}

    Edit:
    Looking at your code now I realized that you are using var x = xmlDoc.getElementsByTagName("name");. This will select EVERY tag name, including the inner one. Try using store to get each one instead of the name and then look for product.

    Also, you are using a hard coded limit in the for loop. Use x.length instead: for (var i=0; i<x.length;i++)
