java使用dom4j读取xml的简单例子

<?xml version="1.0" encoding="UTF-8"?>
<root>
<user>
<id>1</id>
<name>abc</name>
</user>
<user>
<id>2</id>
<name>xyz</name>
</user>
</root>

import java.util.Iterator;
import org.dom4j.*;
import org.dom4j.io.*;

public class Dom4jTest {
public static void main(String[] args) throws DocumentException {
SAXReader reader = new SAXReader();
Document doc = reader.read("test.xml");
Element root = doc.getRootElement();
Element foo;
for (Iterator i = root.elementIterator("user"); i.hasNext();) {
foo = (Element) i.next();
System.out.print("ID:" + foo.elementText("id"));
System.out.println(" Name:" + foo.elementText("name"));
}
}
