PullParser

Question

を使用して属性の値を解析する方法私はGoogleの天気予報APIレスポンスを解析したい... 応答は同様である：

<current_conditions> 
    <condition data="Haze"/> 
    <temp_f data="82"/> 
    <temp_c data="28"/> 
    <humidity data="Humidity: 94%"/> 
    <icon data="/ig/images/weather/haze.gif"/> 
    <wind_condition data="Wind: SW at 12 mph"/> 
    </current_conditions>  

    now i want only temp_c data to use in my app. 
    so how can i get the value of temp using xml pull parser.. 

    right now i m doing like that 

    StringBufferInputStream buffer = new StringBufferInputStream(response); 
     xpp = XmlPullParserFactory.newInstance().newPullParser(); 
     xpp.setInput(buffer, null); 
     int eventType = xpp.getEventType(); 
     while(eventType != XmlPullParser.END_DOCUMENT) 
     { 


      if(eventType == XmlPullParser.START_TAG){ 

       String elementName = xpp.getName(); 
       if(elementName.equals("current_conditions")){ 
        local_pickup = xpp.nextText(); 
        Log.d("database", local_pickup); 
       } 
         } 
        eventType = xpp.next(); 
     } 
     buffer.close(); 

早けれ
