XML解析之二：SAXParse

import java.io.File;
import java.io.FileReader;

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

import org.xml.sax.AttributeList;
import org.xml.sax.HandlerBase;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;

public class Saxxml extends HandlerBase {

    private String currentElement = null;
    private String currentValue = null;

    /**
     * @param args
     */
    public static void main(String[] args) {
        try {
            (new Saxxml()).run("c:\\member.xml");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void run(String filename) throws Exception {

        File file = new File(filename);
        FileReader reader = new FileReader(file);
        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        Saxxml handler = new Saxxml();
        sp.parse(new InputSource(reader), handler);
    }
   
    public void startDocument() throws SAXException {
        System.out.println("starting parse XML file....");
    }
   
   public void startElement(String tag, AttributeList attrs) throws SAXException {
       // currentElement = tag;
       System.out.println(tag);
  }
  public void characters(char[] ch, int start, int length) throws SAXException {
       // currentValue = new String(ch, start, length);
      System.out.println(new String(ch, start, length));
  }
  public void endElement(String name) throws SAXException {
//    if (currentElement.equals(name)) {
//        table.put(currentElement, currentValue);
//    }
  }
 
  public void endDocument() throws SAXException {
      System.out.println("end parse XML file!");
  }
}



AttributeList和HandlerBase在V1.6已经不推荐了。
HandlerBase和DefaultHandler很类似，可以替换。
