你好,我给你举个例子吧.
1.XML文件
<?xml version="1.0" encoding="GB2312" ?>

<resume>
<person id="01">
   <name>张三</name>
   <birthday>03/24/1975</birthday>
   <phone>1111-1111</phone>
   <address>大连</address>
</person>
<person id="02">
   <name>李四</name>
   <birthday>9/26/1978</birthday>
   <phone>2222-2222</phone>
   <address>南京</address>
</person>
<person id="03">

   <birthday>11/09/1979</birthday>
   <phone>3333-3333</phone>
   <address>武汉</address>
</person>
<person id="04">

   <birthday>6/04/1973</birthday>
   <phone>4444-4444</phone>
   <address>青岛</address>
</person>

   <birthday>12/19/1977</birthday>
   <phone>5555-5555</phone>
   <address>上海</address>
</person>
</resume>

2.MyDOMBean.java
package test;

import org.xml.sax.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import java.io.*;

public class MyDOMBean implements java.io.Serializable {
   private static String xmlStr="";
   private static final String PATH="file:///";

   public MyDOMBean() {
   }

   public String getString(){
        return xmlStr;
   }

   public static Document getDocument(String filename) throws Exception {
       xmlStr="";
       DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        // 设定解析的叁数
        dbf.setIgnoringComments(true);
        dbf.setIgnoringElementContentWhitespace(true);
        DocumentBuilder db = dbf.newDocumentBuilder();
        //导入XML文件
        Document doc = db.parse(PATH+filename);

       return doc;
   }

     public void traverseTree(Node node) throws Exception {
         if(node == null) {
            return;
         }
         int type = node.getNodeType();

         switch (type) {
            // handle document nodes
            case Node.DOCUMENT_NODE: {
               xmlStr+="<tr>";
               traverseTree(((Document)node).getDocumentElement());
               break;
            }
            // handle element nodes
            case Node.ELEMENT_NODE: {
               String elementName = node.getNodeName();
               if(elementName.equals("person")) {
                 xmlStr+="</tr><tr>";
               }
               NodeList childNodes =
               node.getChildNodes();
               if(childNodes != null) {
                  int length = childNodes.getLength();
                  for (int loopIndex = 0; loopIndex <
                  length ; loopIndex++)
                  {
                     traverseTree(childNodes.item(loopIndex));
                  }
               }
               break;
            }
            // handle text nodes
            case Node.TEXT_NODE: {
               String data = node.getNodeValue().trim();
               if((data.indexOf("\n")  <0) && (data.length()> 0)) {
                 xmlStr+="<td>"+data+"</td>";
               }
            }
         }
    }

}

3.jsp文件
<html>
<head>
<title>使用DOM解析器</title>
</head>
<%@ page import="org.w3c.dom.*"%>
<%@ page contentType="text/html;charset=GB2312" %>
<body bgcolor="#CFF1E1">
<center>
<h2>个人履历表（DOM版）</h2>
<table border="1" width="80%">
<tr>
<td>姓名</td>
<td>出生年月</td>
<td>电话号码</td>
<td>居住地</td>
</tr>
<jsp:useBean id="domparser" class="test.MyDOMBean" />
<%
   Document doc = domparser.getDocument(request.getRealPath("/") + "08_02.xml");
   domparser.traverseTree(doc);
   out.print(domparser.getString());
%>
</body>
</html>
