sax解析

继承DefaultHandler，重写这几个方法

package com.shun;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;


public class SaxHandler extends DefaultHandler{
	
	
	
	//标签中的内容
	@Override
	public void characters(char[] ch, int start, int length)
			throws SAXException {
		String str = new String(ch,start,length);
		System.out.println(str);
	}
	//开始解析文档
	@Override
	public void startDocument() throws SAXException {
		
	}
	//开始解析一个节点
	@Override
	public void startElement(String uri, String localName, String qName,
			Attributes attributes) throws SAXException {
		//根据 属性的 名称拿到 属性值
		System.out.println("attribute"+attributes.getValue("sal"));
		System.out.println("uri:"+ uri + "    localName:"+localName +"   qName:"+qName);
	}
	//这个节点解析结束
	@Override
	public void endElement(String uri, String localName, String qName)
			throws SAXException {
	}
	//文档解析结束
	@Override
	public void endDocument() throws SAXException {
	}
}

解析

package com.shun;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

public class ParserTest {

	public static void main(String[] args) throws Exception {
		SAXParserFactory factory = SAXParserFactory.newInstance();
		SAXParser saxParse = factory.newSAXParser();
		String path = ParserTest.class.getResource("/").getPath();
		SaxHandler saxHandler = new SaxHandler();
		saxParse.parse(path + "sax.xml", saxHandler);
		System.out.println(path);
	}
}
