jparce.js

var _ = require('underscore');

		var t = n[p];
		if(_.isUndefined(t)){

	}
	var items = path.split('.');
	return _(items).reduce(function(entity, item){
		return getElement(entity, item);
	}, node);
}

var xml = "<root><test jessie='Home cook'><sub party='crib'>aaaa</sub><food>bbbbbb</food></test></root>"
x2js.parseString(xml, function (err, result) {
    console.log(traverseJson('root', result));
