通过Java读取xml文件内容

需要下载jar包dom4j：https://dom4j.github.io/

package com.zyb.xml;

import java.io.File;
import java.util.Iterator;

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

public class testXml {

	public static void main(String[] args) throws Exception {
		// TODO Auto-generated method stub
		//1.创建SAXReader对象用于读取xml文件
		SAXReader reader = new SAXReader();
		//2.读取xml文件，获得Document对象
		Document doc = reader.read(new File("src/book.xml"));
		//3.获取根元素
		Element root = doc.getRootElement();
		//4.获取根元素下的所有子元素（通过迭代器）
		Iterator<Element> it = root.elementIterator();
		while(it.hasNext()){
			
			Element e = it.next();
			//获取id属性(attribute是属性的意思)
			Attribute id = e.attribute("id");
			System.out.println(id.getName()+" = "+id.getStringValue());
			Element author = e.element("author");
			Element money = e.element("price");
			Element time = e.element("time");
			System.out.println(author.getName()+" = "+author.getStringValue());
			System.out.println(money.getName()+" = "+money.getData());
			System.out.println(time.getName()+" = "+time.getText());
			System.out.println("---------------------------------------------------------------");
		}
	}

}
