Dom解析

import org.dom4j.DocumentException;

public class DomTest {
    public static void main(String[] args) {
        String file =DomTest.class.getResource("sounds.xml").toString();
        DomParser domPar = new DomParser();
        try {
            domPar.parse(file);
        } catch (DocumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
}
}

解析方法：

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 DomParser {

public void parse(String file) throws DocumentException{
    SAXReader domparser = new SAXReader();//创建解析器
    Document doc = domparser.read(file);//使用解析器解析，结果全部存入doc中
    Element root = doc.getRootElement();

    Iterator musicIterator = root.elementIterator();

    while(musicIterator.hasNext()){
        Element music = (Element)musicIterator.next();
        Iterator attrIterator = music.attributeIterator();
        while(attrIterator.hasNext()){
            Attribute arr = (Attribute)attrIterator.next();
            if("id".equals(arr.getName())){
                System.out.println("id："+arr.getValue());
        }
    }
}
    }
}
