待解析的XML
Java代码
< xml version="1.0" encoding="utf-8" >
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 {
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

}
@Override

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);
