How to parse XML using jQuery?


How do I parse XML, and how can I navigate the result using jQuery? Here is my sample XML:

<Pages>
  <Page Name="test">
    <controls>
      <test>this is a test.</test>
    </controls>
  </Page>
  <Page Name = "User">
    <controls>
      <name>Sunil</name>
    </controls>
  </Page>
</Pages>

I would like to find the node by this path Pages -> Page Name -> controls -> test ?

There is the $.parseXML function for this: http://api.jquery.com/jQuery.parseXML/

You can use it like this:

var xml = $.parseXML(yourfile.xml),
  $xml = $( xml ),
  $test = $xml.find('test');

console.log($test.text());

If you really want an object, you need a plugin for that. This plugin for instance, will convert your XML to JSON: http://www.fyneworks.com/jquery/xml-to-json/


you can use .parseXML

var xml='<Pages>
          <Page Name="test">
           <controls>
              <test>this is a test.</test>
           </controls>  
          </Page>
          <page Name = "User">
           <controls>
             <name>Sunil</name>
           </controls>
          </page>
        </Pages>';

jquery

    xmlDoc = $.parseXML( xml ),
    $xml = $( xmlDoc );
    $($xml).each(function(){
       alert($(this).find("Page[Name]>controls>name").text());
     });

I assume you are loading the XML from an external file. With $.ajax(), it's quite simple actually:

$.ajax({
    url: 'xmlfile.xml',
    dataType: 'xml',
    success: function(data){
        // Extract relevant data from XML
        var xml_node = $('Pages',data);
        console.log( xml_node.find('Page[Name="test"] > controls > test').text() );
    },
    error: function(data){
        console.log('Error loading XML data');
    }
});

Also, you should be consistent about the XML node naming. You have both lowercase and capitalized node names (<Page> versus <page>) which can be confusing when you try to use XML tree selectors.


$xml = $( $.parseXML( xml ) );

$xml.find("<<your_xml_tag_name>>").each(function(index,elem){
    // elem = found XML element
});

Have a look at jQuery's .parseXML() [docs]:

var $xml = $(jQuery.parseXML(xml));

var $test = $xml.find('Page[Name="test"] > controls > test');

I went the way of jQuery's .parseXML() however found that the XML path syntax of 'Page[Name="test"] > controls > test' wouldn't work (if anyone knows why please shout out!).

Instead I chained together the individual .find() results into something that looked like this:

$xmlDoc.find('Page[Name="test"]')
       .find('contols')
       .find('test')

The result achieves the same as what I would expect the one shot find.


First thing that pop-up in google results http://think2loud.com/224-reading-xml-with-jquery/ There's no simple way to access xml structure (like you described Pages->pagename->controls->test) in jQuery without any plugins.
