我正在使用SAXParser來解析xml文件。但是我的應用程序只有在解析我的XML文件中的第3項,而忽略rest.Below是我的代碼,我試圖解析XML文件:SAXParser不會解析整個xml文件

主要活動:

public class XMLParsingExample extends Activity { 

    /** Create Object For Bar Class */ 
    Bar barList = null; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     /** Create a new layout to display the view */ 
     LinearLayout layout = new LinearLayout(this); 
     layout.setOrientation(1); 

     /** Create a new textview array to display the results */ 
     TextView colour[]; 
     TextView division[]; 
     TextView rect[]; 

     try { 

      /** Handling XML */ 



      String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/saveObject/new.xml"; 
      File file = new File(path); 
      SAXParserFactory parserFactory=SAXParserFactory.newInstance(); 
      SAXParser saxParser=parserFactory.newSAXParser(); 
      XMLReader reader=saxParser.getXMLReader(); 
      MyXMLHandler myXMLHandler = new MyXMLHandler(); 
      reader.setContentHandler(myXMLHandler); 
      reader.parse(new InputSource(new FileInputStream(file))); 



     } catch (Exception e) { 
      System.out.println("XML Pasing Excpetion = " + e); 
     } 

     /** Get result from MyXMLHandler Bar Object */ 
     barList = MyXMLHandler.barList; 

     /** Assign textview array lenght by arraylist size */ 
     colour = new TextView[barList.getColour().size()]; 
     division = new TextView[barList.getDivision().size()]; 
     rect = new TextView[barList.getRect().size()]; 

     /** Set the result text in textview and add it to layout */ 
     for (int i = 0; i < barList.getRect().size(); i++) { 
      colour[i] = new TextView(this); 
      colour[i].setText("Colour = "+barList.getColour().get(i)); 
      division[i] = new TextView(this); 
      division[i].setText("Division = "+barList.getDivision().get(i)); 
      rect[i] = new TextView(this); 
      rect[i].setText("Rect = "+barList.getRect().get(i)); 

      layout.addView(colour[i]); 
      layout.addView(division[i]); 
      layout.addView(rect[i]); 
     } 

     /** Set the layout view to display */ 
     setContentView(layout); 

    } 
} 

XML處理程序:

要解析
public class MyXMLHandler extends DefaultHandler { 

    Boolean currentElement = false; 
    String currentValue = null; 
    public static Bar barList = null; 

    public static Bar getbarList() { 
     return barList; 
    } 

    public static void setbarList(Bar barList) { 
     MyXMLHandler.barList = barList; 
    } 

    /** Called when tag starts*/ 

    @Override 
    public void startElement(String uri, String localName, String qName, 
      Attributes attributes) throws SAXException { 

     currentElement = true; 

     if (localName.equals("bar")) 
     { 
      /** Start */ 
      barList = new Bar(); 
     } 

    } 

    /** Called when tag closing*/ 
    @Override 
    public void endElement(String uri, String localName, String qName) 
      throws SAXException { 

     currentElement = false; 

     /** set value */ 
     if (localName.equalsIgnoreCase("colour")) 
      barList.setColour(currentValue); 
     else if (localName.equalsIgnoreCase("division")) 
      barList.setDivision(currentValue); 
     else if (localName.equalsIgnoreCase("rect")) 
      barList.setRect(currentValue); 



    } 

    /** Called to get tag characters */ 
    @Override 
    public void characters(char[] ch, int start, int length) 
      throws SAXException { 

     if (currentElement) { 
      currentValue = new String(ch, start, length); 

      currentElement = false; 
     } 

    } 

} 

酒吧類

public class Bar { 
    /** Variables */ 
    private ArrayList<String> colour = new ArrayList<String>(); 
    private ArrayList<String> division = new ArrayList<String>(); 
    private ArrayList<String> rect = new ArrayList<String>(); 


    /** In Setter method default it will return arraylist 
    * change that to add */ 

    public ArrayList<String> getColour() { 
     return colour; 
    } 

    public void setColour(String name) { 
     this.colour.add(name); 
    } 

    public ArrayList<String> getDivision() { 
     return division; 
    } 

    public void setDivision(String division) { 
     this.division.add(division); 
    } 

    public ArrayList<String> getRect() { 
     return rect; 
    } 

    public void setRect(String rect) { 
     this.rect.add(rect); 
    } 

} 

XML文件:

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?> 
<bar> 
    <colour>Blue</colour> 
    <division>8898</division> 
    <rect>33</rect> 
</bar> 
<bar> 
    <colour>Red</colour> 
    <division>65</division> 
    <rect>6876</rect> 
</bar> 
<bar> 
    <colour>Black</colour> 
    <division>65</division> 
    <rect>6876</rect> 
</bar> 
<bar> 
    <colour>Yellow</colour> 
    <division>65</division> 
    <rect>6876</rect> 
</bar> 
<bar> 
    <colour>Red</colour> 
    <division>65</division> 
    <rect>6876</rect> 
</bar> 

任何人都可以看到我要去哪裏錯了嗎?

做喲實際上發佈整個XML? – Blackbelt 2013-02-25 16:37:45

有什麼特別的原因,你爲什麼要存儲顏色,divions和rects的集合,而不是存儲一組酒吧? – Perception 2013-02-25 16:37:57

是的,這是整個XML。我正在嘗試存儲具有上述屬性的酒吧集合。我做錯了嗎? – DMC 2013-02-25 16:43:05
