android - xml が正しく解析されないのはなぜですか?

Question

以下のようにxmlを解析したいと思います。実際にデバッグしようとしているので、startElement()メソッド内の School タグに制御が行きません。

<response>
 <school>
   <School>
      <id>1</id>
      <school_name>ABC</school_name>
      <logo/>
      <phone>+91-9764239061</phone>
   </School>
 </school>
</response>

• 私のコードは次のとおりです。

  private static final String TAG = SchoolParser.class.getName().toString(); プライベート リスト schoolListData ; プライベート ブール値 isSuccess; 私立学校; プライベート StringBuffer バッファ。

  private boolean debug = true;
  
  
  public List<School> getSchoolListData(){
      return schoolListData;
  }
  
  
  @Override
  public void startDocument() throws SAXException {
      super.startDocument();
      schoolListData = new ArrayList<School>();
  }
  
  
  @Override
  public void startElement(String uri, String localName, String qName,
          Attributes attributes) throws SAXException {
      super.startElement(uri, localName, qName, attributes);
      Log.d("data in School Parser", "Inside");
      if(localName.equals("School")){
          printInfoLog("New school======>");
          school = new School();
  
      }else if(localName.equals("id")){
          Log.d("data in School Parser inside Localin", "Inside Local");
  
      }else if(localName.equals("school_name")){
  
      }else if(localName.equals("logo")){
  
      }else if(localName.equals("phone")){
  
      }
  
      Log.d("data in School Parser inside Localout", "Inside Local");
  
  }
  
  
  @Override
  public void characters(char[] ch, int start, int length)
          throws SAXException {
      super.characters(ch, start, length);
      buffer.append(new String(ch, start, length));
      printInfoLog(buffer.toString());
  }
  
  
  
  @Override
  public void endElement(String uri, String localName, String qName)
          throws SAXException {
      super.endElement(uri, localName, qName);
  
      if(localName.equals("School")){
          printInfoLog("Add New School======>");
          schoolListData.add(school);
          school =null;
      }else if(localName.equals("id")){
          school.setId(Integer.parseInt(buffer.toString().trim()));
      }else if(localName.equals("school_name")){
          school.setSchoolName(buffer.toString().trim());
      }else if(localName.equals("logo")){
          school.setLogo(buffer.toString().trim().getBytes());
      }else if(localName.equals("phone")){
          school.setPhn_no(buffer.toString().trim());
      }
      //      int size = buffer.length(); 
      //      buffer.delete(0, size);
      Log.i("buffer is empty", ""+buffer.toString());
  }
  
  @Override
  public void endDocument() throws SAXException {
      super.endDocument();
      isSuccess = false;
  }
  
  private void printInfoLog(String msg){
      if(debug ){
          Log.i(TAG, msg);
      }
  }
  

  }

これを変える

if(localName.equals("School")){
    printInfoLog("Add New School======>");
    schoolListData.add(school);
    school =null;
}else if(localName.equals("id")){
    school.setId(Integer.parseInt(buffer.toString().trim()));
}else if(localName.equals("school_name")){
    school.setSchoolName(buffer.toString().trim());
}else if(localName.equals("logo")){
    school.setLogo(buffer.toString().trim().getBytes());
}else if(localName.equals("phone")){
    school.setPhn_no(buffer.toString().trim());
}

に

if(qName.equals("School")){
    printInfoLog("Add New School======>");
    schoolListData.add(school);
    school =null;
}else if(qName.equals("id")){
    school.setId(Integer.parseInt(buffer.toString().trim()));
}else if(qName.equals("school_name")){
    school.setSchoolName(buffer.toString().trim());
}else if(qName.equals("logo")){
    school.setLogo(buffer.toString().trim().getBytes());
}else if(qName.equals("phone")){
    school.setPhn_no(buffer.toString().trim());
}
