Deserialize xml in javascript

Question

Suppose to have an xml like this:

   <?xml version="1.0" encoding="UTF-8"?>
 <Langs>
<dirs>
  <string>uk-fr</string>
  <string>uk-it</string>
  <string>uk-pl</string>
  <string>uk-tr</string>
</dirs>
<langs>
  <Item key="af" value="Afrikaans" />
  <Item key="ar" value="Arabic" />
  <Item key="az" value="Azerbaijani" />
  <Item key="ba" value="Bashkir" />
  <Item key="be" value="Belarusian" />
 </langs>
</Langs>

How can I get an array that contains the key of each item? Using javascipt? An object as this:

  var array = [af,ar,az,ba,be]

You can use DOMParser and then work with the document it returns. (I'm not at a computer now so can't try it out and give an example.) — gcampbell

@gcampbell The DOMParser is an experimental feature and may not be supported everywhere. — Soubhik Mondal

@BlazeSahlzen stackoverflow.com/a/7951947/6303733, caniuse.com/#search=domparser, compare with jquery.com/browser-support — gcampbell

Sorry for the late reply.

Here's an example code on how to use jQuery.parseXML to solve the problem:

var xml_string = 'your xml string';

var output = $.parseXML(xml_string); // <-------- parsing using jQuery.parseXML

var array = []; // <----------------------------- array for storing the keys

// iterating over the elements where selector 'langs>Item' matches in the parsed XML
// and retrieving the key values and pushing them into the array
$('langs>Item', output).each(function(i, e) {
  array.push($(e).attr('key'));
});

// display the output
console.log(array);

Here's a fiddle.
