I have the following method which calls a POST service and it returns XML which I want to put the attributes of the element into a HashMap

The XML format is:

```
<?xml version="1.0"?><paul><ncresponse
atA="14"
atB="10452775"
atC="0">
</ncresponse></paul>

```

The method I want to tidy up is:

```
private HashMap<String, String> myMethod(URL url) throws Exception{
    String dataToSend = createUrlParameters();
    HttpURLConnection connection = null;
    HashMap<String, String> keyValues = new HashMap<String, String>();

    try {
        //Create connection
        connection = (HttpURLConnection)url.openConnection();
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        connection.setRequestProperty("Content-Length", "" + Integer.toString(dataToSend.getBytes().length));
        connection.setRequestProperty("Content-Language", "en-US");

        connection.setUseCaches(false);
        connection.setDoInput(true);
        connection.setDoOutput(true);

        //Send request
        DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
        wr.writeBytes(dataToSend);
        wr.flush();
        wr.close();

        //Get Response
        InputStream is = connection.getInputStream();
        BufferedReader rd = new BufferedReader(new InputStreamReader(is));
        String line;
        StringBuffer response = new StringBuffer();

        while((line = rd.readLine()) != null) {
            response.append(line);
            response.append('\r');
        }

        rd.close();

        System.out.println(response.toString());

        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        org.xml.sax.InputSource inStream = new org.xml.sax.InputSource();
        inStream.setCharacterStream(new java.io.StringReader(response.toString()));
        Document doc = dBuilder.parse(inStream);
        doc.getDocumentElement().normalize();

        NodeList nList = doc.getElementsByTagName("ncresponse");

        for (int temp = 0; temp < nList.getLength(); temp++) {
           Node nNode = nList.item(temp);
           if (nNode.getNodeType() == Node.ELEMENT_NODE) {
               Element eElement = (Element) nNode;
               NamedNodeMap attrs = eElement.getAttributes();
                int len = attrs.getLength();
                for (int i=0; i<len; i++) {
                    Attr attr = (Attr)attrs.item(i);
                    //System.out.println(" " + attr.getNodeName() + "=\"" + attr.getNodeValue() + "\"");
                    keyValues.put(attr.getNodeName(), attr.getNodeValue());
                }
            }
        }

        return keyValues;
    } catch (Exception e) {
        e.printStackTrace();

        return null;
    } finally {

        if(connection != null) {
            connection.disconnect();
        }
    }

```

Thanks in advance guys.
