那的DefaultHandler：

public class StudyHandler extends DefaultHandler { 
private List<Track> track; 
private Track currentTrack; 
private StringBuilder builder; 

boolean isTitle = false; 

public List<Track> getMessages() { 
    return this.track; 
} 

@Override 
public void characters(char[] ch, int start, int length) 
     throws SAXException { 
    super.characters(ch, start, length); 
    builder.append(ch, start, length); 
    if (isTitle) { 
     currentTrack.title = builder.toString(); 
    } 
} 

@Override 
public void startDocument() throws SAXException { 
    super.startDocument(); 

    track = new ArrayList<Track>(); 
    builder = new StringBuilder(); 
} 

@Override 
public void startElement(String uri, String localName, String name, 
     Attributes attributes) throws SAXException { 
    super.startElement(uri, localName, name, attributes); 
    String value = localName.trim(); 
    if (value.equalsIgnoreCase("ITEM")) { 
     this.currentTrack = new Track(); 
    } else if (value.equalsIgnoreCase("TITLE")) { 
     isTitle = true; 
    } 

} 

@Override 
public void endElement(String uri, String localName, String name) 
     throws SAXException { 
    super.endElement(uri, localName, name); 

    if (this.currentTrack != null) { 
     if (localName.equalsIgnoreCase("TITLE")) { 
      isTitle = false; 
     } else if (localName.equalsIgnoreCase("ITEM")) { 
      track.add(currentTrack); 
     } 
     builder.setLength(0); 
    } 
} 
}

当您尝试跟踪每个开始/结束标记操作，或在调试模式下，你是否注意到，解析器解析标签？
