I need to load and read an XML file using JavaScript.
The following code works fine in Firefox, IE and Opera:
function loadXMLDoc(dname) {
var xmlDoc
// Internet Explorer
try {
xmlDoc = new ActiveXObject('Microsoft.XMLDOM')
}
catch (e) {
// Firefox, Opera, etc.
try {
xmlDoc = document.implementation.createDocument('', '', null)
}
catch (e) {
alert(e.message)
}
}
try {
xmlDoc.async = false
xmlDoc.load(dname)
return xmlDoc
}
catch (e) {
alert(e.message)
}
return null
}
But executing this code in Chrome gives me this error:
Object# has no method "load"
Legacy Code
document.implementation.createDocument
does not work on Chrome and Safari.
Use XMLHttpRequest
instead when possible:
function loadXMLSync(url) {
try {
// Prefer XMLHttpRequest when available
var xhr = new XMLHttpRequest()
xhr.open('GET', url, false)
xhr.setRequestHeader('Content-Type', 'text/xml')
xhr.send()
return xmlhttp.responseXML
}
catch (e) {
// XMLHttpRequest not available, fallback on ActiveXObject
try {
var activex = new ActiveXObject('Microsoft.XMLDOM')
activex.async = false
activex.load(url)
return activex
}
catch (e) {
// Neither XMLHttpRequest or ActiveXObject are available
return undefined
}
}
}
Modern Browsers
If you're targeting modern browsers (> IE6), just use XMLHttpRequest:
function loadXMLSync(url) {
var xhr = new XMLHttpRequest()
xhr.open('GET', url, false)
xhr.setRequestHeader('Content-Type', 'text/xml')
xhr.send()
return xhr.responseXML
}
On MDN, there is guidance to use XMLHttpRequest. But it isn't clear from DOMImplementation.createDocument until you drill into the return type and see that XMLDocument is not supported in Google Chrome. The example on W3Schools uses XMLHttpRequest.
follow this to print,load,append xml data.Here xml is stored as string inside javascript.This method works in chrome,firefox hopes it will work in others too
txt="<papers>"+"<paper>"+
"<author>athor name</author>"+
"<title>title</title>"+
"<path>path</path>"+
"<track>which tack</track>"+
"</paper>"+
"<paper>"+
"<author>athor name</author>"+
"<title>title</title>"+
"<path>path</path>"+
"<track>which tack</track>"+
"</paper>"+
"<paper>"+
"<author>athor name</author>"+
"<title>title</title>"+
"<path>path</path>"+
"<track>which tack</track>"+
"</paper>"+
"<papers>";
if (window.DOMParser)
{
parser=new DOMParser();
xmlDoc=parser.parseFromString(txt,"text/xml");
}
else // Internet Explorer
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.loadXML(txt);
}
x=xmlDoc.getElementsByTagName("paper");
for (var i = 0; i < x.length; i++) {
var athor =x[i].childNodes[0].firstChild.nodeValue;
var title = x[i].childNodes[1].firstChild.nodeValue;
var path = x[i].childNodes[2].firstChild.nodeValue;
var tack =x[i].childNodes[3].firstChild.nodeValue;
//do something with these values...
//each iteration gives one paper details
var xml=document.getElementById("element_id");//<div id="element_id"></div>
var li = document.createElement("br");// create a new <br>
newlink = document.createElement('A'); // creating an <a> element
newlink.innerHTML = athor;// adding <a>athor value here</a>
newlink.setAttribute('href', path);// <a href="path"></a>
newlink.appendChild(li);// <a href="path">athor</a><br>
document.getElementById("element_id").appendChild(newlink);
//finaly it becomes <div id="element_id"><a href="path">athor</a><br></div>
}

Add
var xhr = new XMLHttpRequest();
xhr.open("GET", "/example/xdom/books.xml", false);
xhr.send(null);
xmlDoc = xhr.responseXML.documentElement;
return xmlDoc;
in catch
statement. Like below:
function loadXMLDoc(dname) {
var xmlDoc
// Internet Explorer
try {
xmlDoc = new ActiveXObject('Microsoft.XMLDOM')
}
catch (e) {
// Firefox, Opera, etc.
try {
xmlDoc = document.implementation.createDocument('', '', null)
}
catch (e) {
alert(e.message)
}
}
try {
xmlDoc.async = false
xmlDoc.load(dname)
return xmlDoc
}
catch (e) {
//alert(e.message)
// For Chrome
var xhr = new XMLHttpRequest();
xhr.open("GET", "/example/xdom/books.xml", false);
xhr.send(null);
xmlDoc = xhr.responseXML.documentElement;
return xmlDoc;
}
return null
}
