xml文件：

　　Xml代碼

　　

<?xml version="1.0" encoding="GB2312"?><RESULT><VALUE><NO>A1234</NO><ADDR>河南省鄭州市</ADDR></VALUE><VALUE><NO>B1234</NO><ADDR>河南省鄭州市二七區</ADDR></VALUE></RESULT>

　　第一種 DOM 實現方法：

　　Java代碼

　　

import java.io.File;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import org.w3c.dom.Document;import org.w3c.dom.NodeList;public class MyXMLReader2DOM {public static void main(String arge[]) {long lasting = System.currentTimeMillis();try {File f = new File("data_10k.xml");DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();DocumentBuilder builder = factory.newDocumentBuilder();Document doc = builder.parse(f);NodeList nl = doc.getElementsByTagName("VALUE");for (int i = 0; i < nl.getLength(); i++) {System.out.print("車牌號碼:"+ doc.getElementsByTagName("NO").item(i).getFirstChild().getNodeValue());System.out.println("車主地址:"+ doc.getElementsByTagName("ADDR").item(i).getFirstChild().getNodeValue());System.out.println("運行時間：" + (System.currentTimeMillis() - lasting)+ "毫秒");}}} catch (Exception e) {e.printStackTrace();}}}

　　第二種，DOM4J實現方法：

　　Java代碼

　　

import java.io.*;import java.util.*;import org.dom4j.*;import org.dom4j.io.*;public class MyXMLReader2DOM4J {public static void main(String arge[]) {long lasting = System.currentTimeMillis();try {File f = new File("data_10k.xml");SAXReader reader = new SAXReader();Document doc = reader.read(f);Element root = doc.getRootElement();Element foo;for (Iterator i = root.elementIterator("VALUE"); i.hasNext();) {foo = (Element) i.next();System.out.print("車牌號碼:" + foo.elementText("NO"));System.out.println("車主地址:" + foo.elementText("ADDR"));}System.out.println("運行時間：" + (System.currentTimeMillis() - lasting)+ "毫秒");}} catch (Exception e) {e.printStackTrace();}}}

　　第三種 JDOM實現方法：

　　Java代碼

　　

import java.io.*;import java.util.*;import org.jdom.*;import org.jdom.input.*;public class MyXMLReader2JDOM {public static void main(String arge[]) {long lasting = System.currentTimeMillis();try {SAXBuilder builder = new SAXBuilder();Document doc = builder.build(new File("data_10k.xml"));Element foo = doc.getRootElement();List allChildren = foo.getChildren();for (int i = 0; i < allChildren.size(); i++) {System.out.print("車牌號碼:"+ ((Element) allChildren.get(i)).getChild("NO").getText());System.out.println("車主地址:"+ ((Element) allChildren.get(i)).getChild("ADDR").getText());}System.out.println("運行時間：" + (System.currentTimeMillis() - lasting)+ "毫秒");}} catch (Exception e) {e.printStackTrace();}}}

　　第四種SAX實現方法：

　　Java代碼

　　

import javax.xml.parsers.SAXParser;import javax.xml.parsers.SAXParserFactory;import org.xml.sax.Attributes;import org.xml.sax.InputSource;import org.xml.sax.SAXException;import org.xml.sax.helpers.DefaultHandler;public class MyXMLReader2SAX extends DefaultHandler {java.util.Stack tags = new java.util.Stack();public MyXMLReader2SAX() {super();}public static void main(String args[]) {long lasting = System.currentTimeMillis();try {SAXParserFactory sf = SAXParserFactory.newInstance();SAXParser sp = sf.newSAXParser();MyXMLReader2SAX reader = new MyXMLReader2SAX();sp.parse(new InputSource("data_10k.xml"), reader);} catch (Exception e) {e.printStackTrace();}System.out.println("運行時間：" + (System.currentTimeMillis() - lasting)+ "毫秒");}public void characters(char ch[], int start, int length)throws SAXException {String tag = (String) tags.peek();if (tag.equals("NO")) {System.out.print("車牌號碼：" + new String(ch, start, length));}if (tag.equals("ADDR")) {System.out.println("地址:" + new String(ch, start, length));}}public void startElement(String uri, String localName, String qName,Attributes attrs) {tags.push(qName);}}轉載： http://www.jz123.cn/text/2229619.html
