當前程式碼為：

 if(eventType == XmlPullParser.START_TAG) {
            soapResponse= xpp.getName().toString();

            if (soapResponse.equals("EditorialOffice")){  
                eventType = xpp.next();
                if (xpp.getText()!=null){
                editorialOffice += xpp.getText();
                }
            }   
            else if (soapResponse.equals("EditorialBoard")){  
                eventType = xpp.next();
                if (xpp.getText()!=null){
                editorialBoard += xpp.getText();
                }
            }
            else if (soapResponse.equals("AdvisoryBoard")){  
                eventType = xpp.next();
                if (xpp.getText()!=null){
                advisoryBoard += xpp.getText();
                }
            }   
        }
        eventType = xpp.next();
     }
 

可重構為：

Map<String,String> map = new HashMap<String,String>();
map.put("EditorialOffice","");
map.put("EditorialBoard","");
map.put("AdvisoryBoard","");
// could make constants for above Strings, or even an enum

if(eventType == XmlPullParser.START_TAG) {
    soapResponse= xpp.getName().toString();
    String current = map.get(soapResponse);
    if (current != null) {
        eventType = xpp.next();
        if (xpp.getText()!=null){
            map.put( soapResponse, current += xpp.getText());
        }
    }
    eventType = xpp.next();
}
