Load XML using javascript [works with all browser]

When ever we wants to load and parse xml using javascript. we face a issue most of time is that the script works with one browser but not works with other.
Below script will work on all browsers including [safari,mizila firefox, crome]:

function loadxml() {
        var xmlFeed = "xmldata/wfc20100915.xml";
        if (window.ActiveXObject) {
            var errorHappendHere = "Check Browser and security settings";
            xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
            xmlDoc.async = false;
            xmlDoc.load(xmlFeed);
        }
        else if (window.XMLHttpRequest) {
            var errorHappendHere = "Error handling XMLHttpRequest request";
            var d = new XMLHttpRequest();
            d.open("GET", xmlFeed, false);
            d.send(null);
            xmlDoc = d.responseXML;
        } else {
            var errorHappendHere = "Error.";
            xmlDoc = document.implementation.createDocument("", "", null);
            xmlDoc.async = false;
            xmlDoc.load(xmlFeed);
        }
       
        
        var tmp = readXML();
     
        return tmp;
    }
   //below code is to read xml
    function readXML() {

        var labels = xmlDoc.getElementsByTagName('node');       
            arr = new Array();
        var counter = 0;     
   for (i = 0; i < labels.length/ 10; i++) {
   {
   if (labels[i].childNodes.length >= 9) {
     arr[counter] = new Array(5);
     arr[counter][0] = parseFloat(labels[i].childNodes[1].textContent);
     arr[counter][1] = parseFloat(labels[i].childNodes[3].textContent);
     arr[counter][2] = parseFloat(labels[i].childNodes[5].textContent);
     arr[counter][3] = parseFloat(labels[i].childNodes[7].textContent);
     arr[counter][4] = parseFloat(labels[i].childNodes[9].textContent);
     counter++;
                                }
                           
                        }

        return arr;

    }
