SAX

package test.xml;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.Attributes;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

/**
* 使用 SAX 读取XML文件。

*/
public class TestXMLBySAX extends DefaultHandler {
java.util.Stack tags = new java.util.Stack();

public static void main(String args[]) {
    long lasting = System.currentTimeMillis();
    System.out.println("Read By SAX");
    try {
      // 构建工厂
      SAXParserFactory sf = SAXParserFactory.newInstance();
      SAXParser sp = sf.newSAXParser();
      // 构建处理类，每个标签都会让处理类进行解析
      TestXMLBySAX reader = new TestXMLBySAX();
      // 解析
      sp.parse(new InputSource("text.xml"), reader);
    } catch (Exception e) {
      e.printStackTrace();
    }
    System.out.println("运行时间：" + (System.currentTimeMillis() - lasting) + "毫秒");

@Override
public void characters(char ch[], int start, int length) throws SAXException {
    String tag = (String) tags.peek();
    if (tag.equals("NO")) {
      System.out.println("车牌号码：" + length + new String(ch, start, length));
    }
    if (tag.equals("ADDR")) {
      System.out.println("地址:" + length + new String(ch, start, length));

}

@SuppressWarnings("unchecked")
@Override

xml文件：

<?xml version="1.0" encoding="GB2312"?>
<RESULT>
<VALUE>    　　
    <NO>A1234</NO>    　　
    <ADDR>四川省XX县XX镇XX路X段XX号</ADDR>
</VALUE>
<VALUE>    　　
    <NO>B1234</NO>    　　
    <ADDR>四川省XX市XX乡XX村XX组</ADDR>
</VALUE>
</RESULT>
