编写一个Java程序，使用DOM解析器解析下列XML文件用dom4j解析，非常快，具体怎么解析
SAXReader reader = new SAXReader();
String filePath = "c:/abc.xml";
File file = new File(filePath);
Document document = reader.read(file);// 读取XML文件
Element root = document.getRootElement();// 得到根节点
Element select = root.element("select");
for (Iterator i = select.nodeIterator(); i.hasNext();) {
Object obj = i.next();
String content = "";
if (obj instanceof Text) {
content = ((Text)obj).getText().replaceAll("\n", "").trim();
JAVA代码解析方法返回的XML数据，分别取出item标签中的值package com;
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;
public class TestXML {
public static void main(String[] args) {
StringBuffer sb=new StringBuffer("data");
sb.append("message");
sb.append("status6/status");
sb.append("value识别成功/value");
sb.append("/message");
sb.append("cardsinfo");
sb.append("card type='6'");
sb.append("item desc='保留'![CDATA[轻轻巧巧]]/item");
sb.append("item desc='号牌号码'![CDATA[*888084]]/item");
sb.append("/card");
sb.append("/cardsinfo");
sb.append("/data");
try {
DocumentBuilderFactory factory = DocumentBuilderFactory
.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder
.parse(new InputSource((new StringReader(sb.toString()))));
NodeList list = doc.getElementsByTagName("item");
System.out.println("------------节点item如下java代码讲解器：------------");
for (int i = 0; ilist.getLength(); i++) {
Node book = list.item(i);
System.out.println("\t节点=" + i + "\t内容="
+ book.getFirstChild().getNodeValue());
