out.write(body);

          System.out.println("Encoding is " + inputStream.getEncoding());
          BufferedReader in = new BufferedReader(inputStream);
String xmlString="";
String line;
while((line=in.readLine())!=null){
     xmlString+=line;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(new InputSource(new StringReader(xmlString)));
NodeList nl = document.getElementsByTagName("City");
for (int count = 0; count < nl.getLength(); count++) {  
Node n = nl.item(count);
System.out.println(n);
out.close();
in.close();
}

There are no "City" elements in the XML. In fact, as with your post yesterday, there is very very little in the XML.
Also, there is no need to create a String of the response. You can use the reader directly to in the InputSource.
