解析POST请求传递的XML参数

平常可能做得比较多是的解析json传参，如下

public static JSONObject parseRequestToJson(HttpServletRequest request, String charset) throws Exception {
		return new JSONObject(getPostString(request, charset));
	}

	public static String getPostString(HttpServletRequest req, String charset) {
		BufferedReader br = null;
		StringBuilder sb = new StringBuilder();
		try {
			br = new BufferedReader(new InputStreamReader((), charset));
			String temp = "";
			while ((temp = ()) != null) {
				(temp);
				(());
			}
		} catch (Exception e) {
			();
		} finally {
			try {
				if (br != null) {
					();
				}
			} catch (Exception e1) {
				();
			}
		}
		return ();
	}

main{
    //得到json对象
    JSONObject jo = parseRequestToJson(request,"utf-8");

    //或则使用fastjson
    Map<String,String[]> jsonFromSdkServer = ();
	String response_key = ().iterator().next()[0];
	JSONObject jsonParams = (response_key);
}

现在主要说说xml格式的怎么获取：

//其实也就4行代码
//得到post传递过来的xml的string
String xml = ("xml");
//DOM解析器工厂
 dbf = ();
//DOM解析器对象     
 db = (); 
//把得到的执行解析
org. parse = (new ByteArrayInputStream(()));
//得到xml中例如<name>haha</name>
String name = ("name").item(0).getFirstChild().getNodeValue();
//输出haha
(name);
