Cross platform access to the cordova config.xml file.

// And sample use :

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", cordova.configPath, true);
    xhr.send();
}
