How to get separate child node values

Question

    <hotel hotelCode="FR000715" hotelRating="3STR">
        <hotelName>Kyriad Paris Porte D'Ivry</hotelName>
        <hotelChain code="">Simply Hotels</hotelChain>
        <city code="FRIVS" standard="LOCODE">Ivry-Sur-Seine</city>
        <geoLocalization latitude="48.819761" longitude="2.376128"/>
        <address>1-11, Rue René Villars 94200 Ivry-Sur-Seine</address>
        <phone>00 33 1 46 71 00 17</phone>
        <fax>00 33 1 46 58 91 00</fax>
        <email>email@test.com</email>
    </hotel>

I want to get hotelCode, hotelRating,hotelName,city,geoLocalization from above code

here is my code :

        DOMParser parser = DOMParser.getInstance();
        parser.parse(responseStr);
        Document document = parser.getDocument();
        NodeList response = document.getElementsByTagName("hotel");

        for (int hd = 0; hd < response.getLength(); hd++) {

            for (int j = 0; j < response.item(hd).getChildNodes().getLength(); j++) {
                Node referenceChild = response.item(hd).getChildNodes().item(j);

                if (null != referenceChild.getLocalName()) {
                    if (referenceChild.getLocalName().equals("hotelName")) {
                        hotelName = referenceChild.getFirstChild().getNodeValue();
                    }
                }
            }
        }

Only I can only receive hotelName. But not other tags. I want to get all child nodes values separately.

You can use "element.getAttribute"

for (int hd = 0; hd < response.getLength(); hd++) {
        Node nNode = response.item(hd);
        if (nNode.getNodeType() == Node.ELEMENT_NODE) {
              Element eElement = (Element) nNode;
              hotelCode=eElement.getAttribute("hotelCode");
              hotelRating=eElement.getAttribute("hotelRating");
            for (int j = 0; j < response.item(hd).getChildNodes().getLength(); j++) {
                Node referenceChild = response.item(hd).getChildNodes().item(j);

                if (null != referenceChild.getLocalName()) {
                    if (referenceChild.getLocalName().equals("hotelName")) {
                        hotelName = referenceChild.getFirstChild().getNodeValue();
                    }
                    else if (referenceChild.getLocalName().equals("city")) {
                        city = referenceChild.getFirstChild().getNodeValue();
                    }
                    else if (referenceChild.getLocalName().equals("geoLocalization")) {
                        if (referenceChild.getNodeType() == Node.ELEMENT_NODE) {
                            Element eChildElement = (Element) referenceChild;
                            latitude=eChildElement.getAttribute("latitude");
                            longitude=eChildElement.getAttribute("longitude");
                        }
                    }
                }
            }
            }
        }
