How to get corova to load config.xml from subdirectory

Changing it in confighelper.js has no effect, but changing it in cordova.js (line 875 in my file) did load the config.xml file

try {
xhr.open(“get”, “/storebr/config.xml”, true);
xhr.send();
} catch(e) {
fail(’[Browser][cordova.js][readConfig] Could not XHR config.xml: ’ + JSON.stringify(e));
}
