Access config.xml preferences from JavaScript plugins

Question

In my project's config.xml I added a custom preference:

<preference name="FooBar" value="Baz" />

Then, in my custom plugin's JavaScript inside <plugin>/www/plugin.js I want to access the value of such feature.

Does Cordova exposes those values to the JavaScript side? I couldn't find any information in the documentation about it.

Tried:

var argscheck = require('cordova/argscheck');
argscheck.getValue('FooBar'); // Returns just FooBar

You could use following code on iOS, WP7, WP8, Windows8, and probably Ubuntu

function readConfig() {
    var xhr = new XMLHttpRequest();
    xhr.addEventListener("load", function () {
        var parser = new DOMParser();
        var doc = parser.parseFromString(xhr.responseText, "application/xml");
        alert("Description : " + 
              doc.getElementsByTagName("description").item(0).textContent);
    });
    xhr.open("get", "../config.xml", true);
    xhr.send();
}

for the Android you have to change path to file from "../config.xml" to "../../android_res/xml/config.xml"
