Android学习笔记_XML文件的解析
XML文件的解析：
方式：
1.DOM
2.SAX

例子：
public class XMLActivity extends Activity{
    private Button parseButton;
    public void onCreate(Bundle saveInstanceState){
       super.onCreate(saveInstanceState);
       setContentView(R.layout.main);
       parseButton =(Button)findViewById(R.id.parseButton);
       parseButton.setOnClickListener(new ParseButtonListener());
    }
    class ParseButtonListener implements OnClickListener{
       public void onClick(View v){
          HttpDownloader hd=new HttpDownloader();
          String resultStr=hd.download("http://192.168.0.1:8081/test/test.xml");
          System.out.println(resultStr);
          try{
             SAXParserFactory factory=SAXParserFactory.newInstance();
             XMLReader reader=factory.newSAXParser().getXMLReader();
             reader.setContentHandler(new MyContentHandler());
             reader.parse(new InputSource(new StringReader(resultStr)));
          }catch(Exception e){
             e.printStackTrace();
          }
       }
    }
}

public calss MyContentHandler extends DefaultHandler{
    String hisname,address,money,sex,status,tagName;
    public void startDocument()throws SAXException{
        System.out.println("===startDocument===");
    }
    public void endDocument()throws SAXException{
        System.out.println("===endDocument===");
    }
    public void startElement(String namespaceURI,String localName,String qName,Attributes attr)throws SAXException{
        if(localName.equals("worker")){
          for(int i=0;i<attr.getLength();i++){
            System.out.ptinln(attr.getLocalName(i)+"="+attr.getValue(i));
          }
        }      
    }
    public void endElement(String namespaceURI,String localName,String qName,Attributes attr)throws SAXException{
