XML is an important part of AJAX. Heck, it's right in the name, "Asynchronous JavaScript and XML", so knowing how to parse XML is equally important. This tutorial will demonstrate how to parse XML using jQuery that should cover almost all cases you'd typically run into.
Using jQuery to parse XML is vaguely reminiscent of LINQ in the recent .NET frameworks. That's a good thing, since LINQ made parsing XML in .NET vastly easier than previous techniques. With jQuery, when you receive XML from a callback, you're not actually getting raw text, you're actually getting a DOM (document object model) that jQuery can traverse very quickly and efficiently to give you the data you need.
Let's start by looking at the example XML document we'll be parsing today. I made a file that contains most things you'd see in a typical XML document - attributes, nested tags, and collections.

The first thing you're going to have to do is write some jQuery to request the XML document. This is a very simple AJAX request for the file.
{
$.ajax({
type: "GET",
url: "jquery_xml.xml",
dataType: "xml",
success: parseXml
});
});
Now that that's out of the way, we can start parsing the XML. As you can see, when the request succeeds, the function parseXML is called. That's where I'm going to put my code. Let's start by finding the author of each tutorial, which are stored as attributes on the Tutorial tag.
{
//find every Tutorial and print the author
$(xml).find("Tutorial").each(function()
{
$("#output").append($(this).attr("author") + "<br />");
});
// Output:
// The Reddest
// The Hairiest
// The Tallest
// The Fattest
}
The quickest way to parse an XML document is to make use of jQuery's powerful selector system, so the first thing I do is call find to get a collection of every Tutorial element. Then I call each, which executes the supplied function on every element. Inside the function body, this now points to a Tutorial element. To get an attribute's value, I simply call attr and pass it the name of what attribute I want. In this example, I have a simple HTML span object with an id of "output". I call append on this element to populate it with data. You would probably do something a little more exciting, but I just wanted a simple way to display the results.
See how easy that is? Let's now look at a slightly more complicated one. Here I want to print the publish date of each tutorial followed by the title.
$(xml).find("Tutorial").each(function()
{
$("#output").append($(this).find("Date").text());
$("#output").append(": " + $(this).find("Title").text() + "<br />");
});
// Output:
// 1/13/2009: Silverlight and the Netflix API
// 1/12/2009: Cake PHP 4 - Saving and Validating Data
// 1/6/2009: Silverlight 2 - Using initParams
// 12/12/2008: Controlling iTunes with AutoHotkey
This is very similar to the previous example, except now the values are stored inside element text instead of attributes. Again, I want to go through every Tutorial tag, so I first use find and each. Once I'm inside a Tutorial, I need to find the Date, so I use find again. To get the text inside an XML element, simply call text. I repeat the same process again for the Title, and that's it.
We've now parsed every piece of information except the categories that each tutorial belongs to. Here's the code to do that.
$(xml).find("Tutorial").each(function()
{
$("#output").append($(this).find("Title").text() + "<br />");
$(this).find("Category").each(function()
{
$("#output").append($(this).text() + "<br />");
});
$("#output").append("<br />");
});
// Output:
// Silverlight and the Netflix API
// Tutorials
// Silverlight 2.0
// Silverlight
// C#
// XAML
// Cake PHP 4 - Saving and Validating Data
// Tutorials
// CakePHP
// PHP
// Silverlight 2 - Using initParams
// Tutorials
// Silverlight 2.0
// Silverlight
// C#
// HTML
// Controlling iTunes with AutoHotkey
// Tutorials
// AutoHotkey
Once again, I get every Tutorial by using find and each. I then get the Title in the same was as the previous example. Since a tutorial can belong to several categories, I call find and each to iterate over each Category element inside a tutorial. Once I'm inside a Category element, I simple print out its contents using the text function.
Being able to parse elements, attributes, and collections should cover almost every form of XML you'd ever see, and making use of jQuery selectors to get the job done makes parsing XML in JavaScript a breeze. That does it for this tutorial. Hopefully we all learned something about jQuery and XML.

01/16/2009 - 12:49
Thanks for the warning! Unfortunately, I didn't think about namespaces when I wrote the article. I guess I should have mentioned somewhere that jQuery doesn't directly support them.

You're definitely right about that. I'll blame that on a copy/paste error. Where I was using this code I had an another function call in that body. I've corrected the post. Thanks for finding it.

Restructure your Xml-File like this:
<math>
<time>1:00pm</time>
</math>
<math>
<time>3:00pm</time>
</math>
<phisic>
<time>1:00pm</time>
</phisic>
<phisic>
<time>3:00pm</time>
</phisic>
</courses>
You can access the xml tags with the following jQuery code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>XML Parsing With jQuery</title>
<script src="jquery-1.2.6.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function()
{
<!-- math -->
$.get('myData.xml', function(d){
var options="";
$(d).find('math').each(function(){
var $time = $(this);
var dropdownvalue = $time.find('time').text();
options += ' <option value="' + dropdownvalue + '">' + dropdownvalue + '</option>\r\n'
})
$("#mymath").html(options);
;
});
<!-- math End -->
<!-- phisic -->
$.get('myData.xml', function(d){
options="";
$(d).find('phisic').each(function(){
var $time = $(this);
var dropdownvalue = $time.find('time').text();
options += ' <option value="' + dropdownvalue + '">' + dropdownvalue + '</option>\r\n'
})
$("#myphisic").html(options);
;
});
<!-- phisic End -->
});
</script>
<body>

i am making a video gallery. i found a flash template that creates xml file.
XML data looks this:

</gallery>
The gallery works. When I click each thumbnails, the FLV runs.
I want to put film description in my markup. How will i do this for every film currently running?
Thank you...

I get confused at:
{
//find every Tutorial and print the author
$(xml).find("Tutorial").each(function()
where is the parameter/variable "xml" declared and instantiated with jquery_xml.xml? Does it magically inherit it from the ajax request. Could someone explain this for me?
11/23/2009 - 09:29
the
xmlvariable is passed into the function automatically by jQuery.parseXmlis supplied to jQuery as part of the ajax request.01/26/2010 - 05:02
Hi, thanks for this tutorial it has been illuminating.
I'v just one problem - it takes about 6-12 seconds to parse.. :( please help, here is my situation:
XML example: (XML is dynamically created)
<RESPONSE xsi:noNamespaceSchemaLocation="http://192.168.xxx.xx:10000/rest/schemas/contacts_response.xsd">
<PARAMETERS>
<Ret_Data>
<contact url="http://192.168.xxx.xx:10000/rest/contact/1">
<CNT_ID>1</CNT_ID>
<CNT_LASTNAME>Marko</CNT_LASTNAME>
<CNT_FIRSTNAME>Matic</CNT_FIRSTNAME>
<CNT_ORGANIZATIONNAME>IT Business Soft</CNT_ORGANIZATIONNAME>
<CNT_TYPE>1</CNT_TYPE>
<CNT_NAME>Marko Matic</CNT_NAME>
</contact>
<contact url="http://192.168.xxx.xx:10000/rest/contact/14044">
...
</contact>
...
... etc (about 1500 CONTACT elements)
</Ret_Data>
</PARAMETERS>
(there are about 1500 'contact' nodes) -> IS IT POSSIBLE THAT IT'S SLOW BECAUSE EACH WILL ITERATE TROUGH EVERY CHILD - CAN I RESTRICT SOMEHOW SOMETHING?)
$(document).ready(function()
{
$.ajax({
type: "GET",
url: "http://192.168.xxx.xx:10000/rest/contacts/",
dataType: "xml",
success: parseXML,
error: err
});
});
function err(xhr, reason, ex)
{
$('#output').append(reason);
}
function parseXML(xml)
{
$(xml).find("contact").each(function()
{
$("#content").append($(this).find("CNT_NAME").text());
$("#content").append(": "+
$(this).find("CNT_ORGANIZATIONNAME").text() +" <br />");
});
}
<div id="title">
<h3>Printing: Contact Name followed by organization</h3>
</div>
<div id="content">
</div>
</body>
BUGS:
1) WORKS IN SAFARI/IE - DOES NOT WORK IN FIREFOX (ParseError - it doesn't even call the ParseXML function, just err)
2) Why so slow?? Why cca 10 seconds?
PLEASE HELP THX
ps.
would it be faster if i used NATIVE DOM METHODS? I really really like jQuery, it's so programmer friendly...

Any way to parse data from an xml file whose tags are not known before?
I mean is there any way to generalize it to parse any xml doc on the go?
04/01/2010 - 08:10
Thanks for your help. It helped finnish my project.
I put a link back as resources used in my blog post: http://samosexp.wordpress.com/2010/04/01/using-xml-linq-and-jquery-for-a-google-maps-store-locator/
This is how I used it to read xml with Json, maybe people read this blog who try to achieve the same thing:
type: "POST",
contentType: "application/json; charset=utf-8",
url: "WebService/StoreService.asmx/GetStoresInfo",
//data: "{}",
dataType: "xml",
error: function(XMLHttpRequest, textStatus, errorThrown) {
$("#output").append(XMLHttpRequest.responseText + "<br />TextStatus: " + textStatus + "<br />ErrorThrown: " + errorThrown);
},
success: function(xml) {
// hier wordt de xml uitgelezen
$(xml).find("store").each(function() {
var storename = $(this).find("name").text();
var latitude = $(this).find("latitude").text();
var longitude = $(this).find("longitude").text();
var point = new GLatLng(latitude, longitude);
var marker = new GMarker(point);
map.addOverlay(marker);
});
map.setUIToDefault();
}
});

I am trying to a simple plain POST with a parameter name and value. But my response is in XML. How do I parse the response, how do I set the data type since my input is plain name value pair. Can I use similar without JSON? I am new the JQurey so I am trying to make is very simple for understanding.
Thank you.

im having a problem with the find() function.
For me it works in firefox and chrome perfectly, but any version of explorer returns 'undefinded'
06/05/2010 - 09:36
Internet Explorer is annoying as usual about this and you need to make exceptions for it. I was writing a photo gallery plugin that reads from XML and every browser except for IE was working great. Here's what I had to do:
url: 'photos.xml',
dataType: ($.browser.msie) ? "text" : "xml", //if Browser is internet explorer, the datatype is text, otherwise xml.
success: getXML,
complete:
06/05/2010 - 09:37
And then in my "success" function, I had to add this:
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.loadXML(xml);
xml = xmlDoc;
}

Thank you Timothy, it worked for me. Thanks a lot....

I have a two xml files.
One contains orders for my store and the other contains order details.
Could I use this jquery scripts to grab the data from one file and the order details from the other file and merge them together?
Example:
xmlfile 1:
<orderid>1</orderid>
<customerid>1</customerid>
<shipfirstname>John</shipfirstname>
<shiplastname>Doe</shiplastname>
<shipaddress1>11111 Where Ever</shipaddress1>
<shipaddress2 />
<shipcity>Yep</shipcity>
<shipstate>MD</shipstate>
<shippostalcode>111111</shippostalcode>
<shipphonenumber>111-111-1111</shipphonenumber>
<shipfaxnumber />
<total_payment_received>0</total_payment_received>
</Orders>
xml file 2:
<orderid>1</orderid>
<productcode>testRZ</productcode>
<options />
</OrderDetails>
I would like to be able the grab all the order details and attach it to the orders.
06/11/2010 - 10:26
I would create two objects to hold the information contained in the two XML files.
{
this.orderid = 0;
this.customerid = 0;
...
this.orderDetails = null;
}
function OrderDetails()
{
this.orderid = 0;
this.productcode = "";
...
}
I would then parse the 2nd XML file into a collection of OrderDetail objects. Then I'd parse the 1st XML file. When each Order is parsed, I'd lookup the corresponding OrderDetails object by the orderid and set the property to that object.
08/01/2010 - 16:55
The Reddest,
I am only getting [object Object] returned as what should be parsed xml parts (see below). I want to do something very similar like you described in your article - inserting a list of customers from an xml file into my html (as list elements).
I obviously have something wrong somewhere in my code that I am unable to find after staring at it for hours ...
I am running jQuery 1.4.2 on Mac OS X 10.6.4. Same in Safari 5 and Firefox.
Any help appreciated.

Oops - posted too early and after staring at it 10 minutes more I found the easy, stupid thing ...
The iteration in the each loop obviously _is_ an object and not [yet ?] a valid [X]HTML snippet that could be inserted as is into the html (although in my case it could ...).
I needed to pick out the attributes [
$(this).attr("xxxx")] or the inner text of the element [$(this).text()] to produces results.I hope that somebody else can profit from that mistake ...

HI. Thanks so much for this article. I've learned a lot. I have one quick question = how can I parse the XML and create a list with a link to a detail page from the same data?
For instance I have a feed where I just want to first display a list with the title but make it a link that will then display all of the detailed desc and info?
thank you !! Any help or pointers would be much appreciated! Ya know, I think that to do the type of manipulation I want, I need to convert the XML to JSON. I'll try that.
cheers, brent

If your xml file has dates for given events (or maybe in your case, dates for live tutorial sessions in your tutorial xml); how would you pull dates from this year (2010) and next (2011), and ones from 'today's date' forward. Also, how would you incorporate it into your jquery request to NOT grab the ones before 'today's date', or after this year (2010).
And how would you differentiate the two years in your xml file as, for instance, you had some tutorial live viewings for tutorials that are a two-day viewing (Sep 10 and 11, 2010 for instance).
10/27/2010 - 01:09
Hi, I was wondering if anybody knows how to get a JSON response from an xml file using ajax.
01/24/2011 - 16:58
This was a huge help, but when I tried to modify it for my situation I come up short. It works perfectly when I appended the output to a div. But I want to set string variables to different languages stored in XML files.
<Module abbrv="hr101" name="Human Rights 101">
<sections>
<section>
<id>00</id>
<file>hr101-00-intro</file>
<label>Welcome</label>
</section>
<section>
<id>A0</id>
<file>hr101-A0-about</file>
<label>About Human Rights</label>
</section>
</sections>
</Module>
I tried...
{
var theXML = $.ajax({
type: "GET",
url: path,
dataType: "xml"
});
return theXML;
}
(I also tried that with a success function that just said return xml; and got the same result)
I then call it like so...
var myModuleName = $(getXML).find('Module').attr('name');
alert('myModuleName='+myModuleName);
The alert says "undefined"
What am I not getting?
01/27/2011 - 10:09
I remained unable to solve this until I happened on the article here: http://techmonks.net/getscript-and-firebug-code
I copy/pasted their final example to the top of my .js file and presto--it works.
A fix for $.getScript() :
getScript: function(url, callback) {
var head = document.getElementsByTagName("head")[0] || document.documentElement;
var script = document.createElement("script");
script.src = url;
// Handle Script loading
{
var done = false;
// Attach handlers for all browsers
script.onload = script.onreadystatechange = function() {
if ( !done && (!this.readyState || this.readyState === "loaded" ||
this.readyState === "complete") ) {
done = true;
//success();
//complete();
if ( callback)
callback();
// Handle memory leak in IE
script.onload = script.onreadystatechange = null;
if ( head && script.parentNode ) {
head.removeChild( script );
}
}
};
}
head.insertBefore( script, head.firstChild );
return undefined;
}
});
01/27/2011 - 10:16
Oh yeah, as you might have guessed I abandoned the .XML file entirely and created a JSON Object within a .js file. I set a cookie for the language, or allow the user to set one from a select, then I use that to construct the path to a language-specific .js file, which I now generate from a mySQL database (using ColdFusion).

Hey Hi,
I have an issue with parsing xml while using jquery for the same :
I am loading content into a div tag and then trying to load XML into the html page using jquery. My problem is that it works for the first two link clicks but after that it does not work. I know i need to rebind the whole thing but i am not able to figure out the way of doing it. Here's the code snippet :
initBinding();
$.ajax({
type: "GET",
url: "../XML/contact.xml",
dataType: ($.browser.msie) ? "text" : "xml",
success: parseXML
});
function parseXML(data) {
if (typeof data == "string") {
xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = true;
xml.loadXML(data);
}
else {
xml = data;
}
var pos = $(".content:first");
$(xml).find('site').each(function(){
var desc = $(this).find('desc').text();
pos.append(desc);
});
}
});
function initBinding()
{
var ajaxResponse = $("html");

Hi All,
I have a requirement.. I have right and left navigation menus and submenus(with links), all these data has to come from the xml using jquery. Organised in Div blocks and we need to just populate the data on these divs.Also there is an attribute (expand) in xml set to either true or false such that we will show/hide div block as default.Below is the snippet
Right navigation should be shown by default and left navigation should be hidden based on the expand value.
Please help me.
Thanks

I want to calculate the time taken for each root by subtracting the arrival tag value with departs tag value. After doing all subtractions I need to find out the trip which has taken least time. Pls post ur ideas

I'd just grab any javascript library capable of parsing that date format. Datejs is the first one I found using a Google search. Create an object to hold the details for each flight and populate a collection of them as you parse the XML.
To calculate the duration of each flight, populate the built-in javascript date object using the values parsed by the date library. The date object has a function, getTime, which returns the milliseconds since the epoch. Get the milliseconds for the departure time and arrival times and subtract them - this will give you the duration of each flight, in milliseconds.
To find the fastest, iterate over the collection of objects and find the one with the smallest duration in milliseconds.

I'm looking to find out how jQuery can parse an XML document where I don't have the parent and child nodes known to me. I'm wondering if there is something that I could use to get me the parent node names and then the children node names underneath the parent.
