解析方法:

[code]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());
        }
    }
}
    }
}
