我要在servlet页面上输出XML 可是怎么换行啊。为什么不能换行

[k87765143]

public String songPageManager(int pageNum){
		String xmlStr="";
		if(pageNum!=0){
			ShowAllSongs sas = new ShowAllSongs();
			Songs sg = new Songs();
			xmlStr = ("<?xml version='1.0' encoding='GBK' ?>"+ "\n\t");
			xmlStr += ("<result name='songsList'>"+ "\n\t");
			xmlStr += ("<songsList>"+ "\n\t");
			try{
				List<Songs> songs = sas.getSongsPaginQuery(pageNum);
				for(int i = 0;i < songs.size();i++){
					sg = songs.get(i);
						xmlStr += ("<songs>");
						xmlStr += ("<songid>" + sg.getSongid() + "</songid>");
						xmlStr += ("<typeid>" + sg.getTypeid() + "</typeid>");
						xmlStr += ("<abc>" + sg.getAbc() + "</abc>");
						xmlStr += ("<songurl>" + sg.getSongurl() + "</songurl>");
						xmlStr += ("<dateandtime>" + sg.getDateandtime() + "</dateandtime>");
						xmlStr += ("<title>" + sg.getTitle() + "</title>");
						xmlStr += ("<singer>" + sg.getSinger() + "</singer>");
						xmlStr += ("<imgb>" + sg.getImgb() + "</imgb>");
						xmlStr += ("<imgs>" + sg.getImgs() + "</imgs>");
						xmlStr += ("<lrc>" + sg.getLrc() + "</lrc>");
						xmlStr += ("<channel>" + sg.getChannel() + "</channel>");
						xmlStr += ("<hits>" + sg.getHits() + "</hits>");
						xmlStr += ("<demo>" + sg.getDemo() + "</demo>");
						xmlStr += ("</songs>");
				}
				xmlStr += "</songsList>";
				System.out.println(xmlStr.toString());
			}catch(Exception e){
				e.printStackTrace();
			}
		}else{
			xmlStr = sendError(90001);
		}

		return xmlStr;
		
	}

下面是 servlet的代码

public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		response.setContentType("text/html;charset=UTF-8");
		String xmlStr = "";
		MyService myservice = new MyService();
		DataOutputStream DateOut = new DataOutputStream(response.getOutputStream());
		XMLWriter writer = new XMLWriter(DateOut);
		int pageNum = 0;
        //获取手机端发送过来的请求数据
		String strPageNum = request.getParameter("pageNum");
		if(strPageNum!=null){
			pageNum = Integer.parseInt(strPageNum);
			//调用方法返回数据
			xmlStr = myservice.songPageManager(pageNum);
			writer.write(xmlStr);
			writer.close();
			DateOut.close();
		}else{
			xmlStr = myservice.sendError(90001);
			writer.write(xmlStr);
			writer.close();
			DateOut.close();
		}
	}

输出的效果 ：


如图 我写了\n\t 似乎不管用啊。
怎么解。

右键看源文件就是换行好了的。 另外这个是错误的： response.setContentType("text/html;charset=UTF-8"); 应该是： response.setContentType("text/XML;charset=GBK"); // 跟你实际输出的XML内容应保持一致

换行用<br>试试看。
