SAX解析XML

待解析的XML

Java代码
<?xml version="1.0" encoding="utf-8"?>
<musices>
    <music>
        <name>Hello</name>
        <size>8622</size>
    </music>
    <music>
        <name>World</name>
        <size>2000</size>
    </music>
</musices>

继承DefaultHandler

Java代码
package cn.edu.xml;

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class MyXmlUtils extends DefaultHandler{
    private boolean isName=false;
    private boolean isSize=false;

    private String myname;
    private String mysize;
    @Override
    public void characters(char[] ch, int start, int length)
            throws SAXException {
        // TODO Auto-generated method stub
        super.characters(ch, start, length);
        if(isName){
            myname=new String(ch,start,length);
        }
        if(isSize)
        {
            mysize=new String(ch,start,length);
        }

    }

    @Override
    public void endDocument() throws SAXException {
        // TODO Auto-generated method stub
        super.endDocument();
    }

    @Override
    public void endElement(String uri, String localName, String name)
            throws SAXException {
        // TODO Auto-generated method stub
        super.endElement(uri, localName, name);
    if(name.equals("name")){
        System.out.println(myname);
    }else if(name.equals("size")){
        System.out.println(mysize);}
    }

    @Override
    public void startDocument() throws SAXException {
        // TODO Auto-generated method stub
        super.startDocument();

    }

    @Override
    public void startElement(String uri, String localName, String name,
            Attributes attributes) throws SAXException {
        // TODO Auto-generated method stub
        super.startElement(uri, localName, name, attributes);
        if(name.equals("name")){
            isName=true;
            System.out.println("one");
        }
        else if(name.equals("size")){
            isSize=true;
            System.out.println("second");
        }

    }

}

对XML进行解析

Java代码
SAXParserFactory sf = SAXParserFactory.newInstance();
        SAXParser sp = sf.newSAXParser();
        MyXmlUtils reader = new MyXmlUtils();
        sp.parse(new File("E:\\music.xml"), reader);
