testdom4j.java

一个用Java调用DOM4J解析XML的例子 比较全面 对初学者很有帮助 高手就不浪费你们的点数了 呵呵

package com.ly;

import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.VisitorSupport;
import org.dom4j.io.SAXReader;

public class TestDom4j
{
	public static void main(String[] args)
	{
		SAXReader sax = new SAXReader();
		try
		{
			Document document = sax.read("a.xml");
			// 得到根元素
			Element root = document.getRootElement();

			Element auel = (Element) root.selectNodes("/books/book[@id='A02']/author").get(0);
			System.out.println(auel.getText());

			// root.accept(new MyVisitor1());

			// //root.elementIterator("book");//得到所用的子元素
			// for (Iterator iter = root.elementIterator(); iter.hasNext();) {
			// Element bookel = (Element) iter.next();
			// //根据属性名称来得到属性
			// String id=bookel.attribute("id").getValue();
			// String author=bookel.element("author").getText();
			// System.out.println(id+"\t"+author);
			// }
		} catch (Exception e)
		{
			e.printStackTrace();
			// TODO: handle exception
		}
	}
}

class MyVisitor1 extends VisitorSupport
{
	public void visit(Element element)
	{
		System.out.println(element.getName());
	}

	public void visit(Attribute attr)
	{
		System.out.println(attr.getName());
	}
}
