一个java解析xml的简单例子

import java.util.Iterator;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;


/**

public class XmlUtils {

	/**
	 * 解析XML文件
	 * @param path  XML文件的路径
	 */
	public static void parserXml(String path){
		SAXReader reader = new SAXReader();
	    try {
			Document document = reader.read(path);
			
			Element root = document.getRootElement();
			
			/**
			 * 遍历XML节点
			 */
			for(Iterator i = root.elementIterator(); i.hasNext();){
				Element  el = (Element )i.next();
				
				System.out.println("userId："+el.elementText("userId"));
				System.out.println("userName："+el.elementText("userName"));
				System.out.println("email："+el.elementText("email"));
				
				System.out.println("============================");
			}
		} catch (DocumentException e) {
			e.printStackTrace();
		}
	}

	public static void main(String[] args) {		
		parserXml("userList.xml");
	}

}
