建站学院（LieHuo.Net）文档 今天来学习一篇实例代码教程：AJAX返回xml代码如何在网页中显示，共为三个部分，代码中都加了注释。
1.PostingXMLExample.java
以下为引用的内容：
PostingXMLExample.java
package javabean;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
public class PostingXMLExample extends HttpServlet
{
protected void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException
{
String xml=readXMLFromRequestBody(request);
response.setContentType("text/xml");
PrintWriter out=response.getWriter();
out.println("Hope said the result is:<Br>"+xml);
out.close();
}
private String readXMLFromRequestBody(HttpServletRequest request)
{
StringBuffer xml=new StringBuffer();
String line=null;
try
{
BufferedReader reader=request.getReader();
while((line=reader.readLine())!=null)
{
xml.append(line);
}
}
catch (Exception e)
{
System.out.println(e.toString());
}
return xml.toString();
}
