13.
14. try {
15. File f = new File("l");
16. DocumentBuilderFactory factory = wInstance();
17. DocumentBuilder builder = wDocumentBuilder();
18. Document doc = builder.parse(f);
19. NodeList nl = ElementsByTagName("VALUE");
20. for (int i = 0; i < nl.getLength(); i++) {
21. System.out.print("车牌号码:"+ ElementsByTagName("NO").item(i).getFirstChild().getNodeValue());
22. System.out.println("车主地址:"+ ElementsByTagName("ADDR").item(i).getFirstChild().getNodeValue());
23. }
24. } catch (Exception e) {
25. e.printStackTrace();
26. }
27. }
28. }

4. import org.dom4j.io.*;
5.
6. public class MyXMLReader2DOM4J {
7. public static void main(String arge[]) {
8. long lasting = System.currentTimeMillis();
9. try {
10. File f = new File("l");
11. SAXReader reader = new SAXReader();
12. Document doc = ad(f);
13. Element root = RootElement();
14. Element foo;
15. for (Iterator i = root.elementIterator("VALUE"); i.hasNext();) {
16. foo = (Element) i.next();
17. System.out.print("车牌号码:" + foo.elementText("NO"));
18. System.out.println("车主地址:" + foo.elementText("ADDR"));
19. }
20. } catch (Exception e) {
21. e.printStackTrace();
22. }
23. }
24. }
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("l"); SAXReader reader = new SAXReader(); Document doc = ad(f); Element root = RootElement(); Element foo; for (Iterator i = root.elementIterator("VALUE"); i.hasNext();) { foo = (Element) i.next(); System.out.print("车牌号码:" + foo.elementText("NO")); System.out.println("车主地址:" + foo.elementText("ADDR")); } } catch (Exception e) { e.printStackTrace(); } } }
第三种 JDOM实现方法：
1. import java.io.*;
2. import java.util.*;
3. import org.jdom.*;
4. import org.jdom.input.*;
5.
6. public class MyXMLReader2JDOM {
7. public static void main(String arge[]) {
8. long lasting = System.currentTimeMillis();
9. try {
10. SAXBuilder builder = new SAXBuilder();
11. Document doc = builder.build(new File("l"));
12. Element foo = RootElement();
13. List allChildren = Children();
14. for (int i = 0; i < allChildren.size(); i++) {
15. System.out.print("车牌号码:"+ ((Element) (i)).getChild("NO").getText());
16. System.out.println("车主地址:"+ ((Element) (i)).getChild("ADDR").getText());
17. }
18. } catch (Exception e) {
19. e.printStackTrace();
20. }
21. }
22. }
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("l")); Element foo = RootElement(); List allChildren = Children(); for (int i = 0; i < allChildren.size(); i++) { System.out.print("车牌号码:"+ ((Element) (i)).getChild("NO").getText()); System.out.println("车主地址:"+ ((Element) (i)).getChild("ADDR").getText()); } } catch (Exception e) { e.printStackTrace(); } } }
