Get attribute of inner node in XML

I have a next XML file

<country name="Абхазия">
<city id="37188" region="27028" head="" type="3" country="Абхазия" part="" resort="" climate="">Новый Афон</city>
</country> 

And i need to get the id attribute from the inner city node. I've done the next code, but i have no idea how to proceed:

        Document doc = parser.getDomElement(xml);
        NodeList nl = doc.getElementsByTagName(KEY_COUNTRY);

        for (int i = 0; i < nl.getLength(); i++) {

            Element e = (Element) nl.item(i);
            String city = parser.getValue(e, KEY_CITY);

        }
