使用JDOM解析XML

JDOM和DOM4J都不是Java官方提供的解析XML的工具包，因为使用JDOM前，你需要引入依赖

<dependency>
	<groupId>org.jdom</groupId>
	<artifactId>jdom2</artifactId>
	<version>2.0.6</version>
</dependency>

使用到的demo.xml如下

<?xml version="1.0" encoding="UTF-8"?>
<persons>
    <person id="person1" >
        <name>simons</name>
        <sex>男</sex>      
        <age>24</age>
        <address>魔都</address> 
	</person>
    <person id="person2" >
       <name>rose</name>
        <sex>女</sex>      
        <age>22</age>
        <address>帝都</address> 
	</person>
</persons>

import org.jdom2.Attribute;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.input.SAXBuilder;
import java.io.File;
import java.util.List;

public class JDOMParseXml {

    public static void main(String[] args) throws Exception {
        SAXBuilder saxBuilder = new SAXBuilder();
        //你也可以将demo.xml放在resources目录下，然后通过下面方式获取
        //InputStream resourceAsStream = JDOMParseXml.class.getClassLoader().getResourceAsStream("demo.xml");
        Document document = saxBuilder.build(new File("D:/demo.xml"));
        Element rootElement = document.getRootElement();
        List<Element> elementList = rootElement.getChildren();
        for (Element element : elementList) {
            List<Attribute> attributes = element.getAttributes();
            for (Attribute attribute : attributes) {
                System.out.println(attribute.getName()+":"+attribute.getValue());
            }
            List<Element> children = element.getChildren();
            for (Element child : children) {
                System.out.println(child.getName()+":"+child.getValue());
            }
        }
    }

}

输出结果如下

id:person1
name:simons
sex:男
age:24
address:魔都
id:person2
name:rose
sex:女
age:22
address:帝都
