我正在开发一个应用程序，其中使用其余的webservice从服务器获取xml。从服务器获得响应（以xml格式）后，我使用Dom解析器将其解析为字符串。以下是我的XML响应的示例结构。如何解析嵌套的xml和检索android中的数据？

下面是我的代码通过使HTTP请求
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpHost proxy = new HttpHost("45.28.19.345", 1234);
httpClient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet, localContext);
HttpEntity httpEntity = httpResponse.getEntity();
xml = getASCIIContentFromEntity(httpEntity);</pre>
若要通过元件节点名称 公共字符串的getValue（元项目获取每个XML子元素值获取XML内容， String str）{Node_N = item.getElementsByTagName（str）; return this.getElementValue（n.item（0））; }
public final String getElementValue(Node elem) {
Node child;
if(elem != null){
if (elem.hasChildNodes()){
for(child = elem.getFirstChild(); child != null; child = child.getNextSibling()){
if(child.getNodeType() == Node.TEXT_NODE ){
return child.getNodeValue();
}
}
}
}
return "";
}
这里是如何检索分析的XML数据。
String newxml = xml.toString();
Document doc = parser.getDomElement(newxml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_ITEM);
// looping through all item nodes <item>
for (int i = 0; i < nl.getLength(); i++) {
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
for(int k = 0; k < doc.getChildNodes().getLength(); k++) {
Element e = (Element) nl.item(k);
// adding each child node to HashMap key => value
map.put(KEY_ID, parser.getValue(e, KEY_ID));
map.put(KEY_NAME, parser.getValue(e, KEY_NAME));
map.put(KEY_COST, "Rs." + parser.getValue(e, KEY_COST));
map.put(KEY_DESC, parser.getValue(e, KEY_DESC));
// adding HashList to ArrayList
menuItems.add(map);</pre>
getDomElement（字符串XML）方法是
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
if(is != null){
is.setCharacterStream(new StringReader(xml));
doc = db.parse(is);
通过使用该逻辑是能够检索简单的XML，但不复杂的XML等我如上所述。有人可以给出一个想法，从嵌套的XML获取数据。在Android的
