アンドロイド：... KSOAP

Question

私は私のWebサービス（SOAP）私はSAXパーサーなしでこの結果を解析することができますどのようにWebサービスから受け取ったこのXML結果との接続を行うとXMLを解析

<maintag> 
<item> 
    <name>AndroidPeople</name> 
    <website category="android">www.androidpeople.com</website> 
</item> 
<item> 
    <name>iPhoneAppDeveloper</name> 
    <website category="iPhone">www.iphone-app-developer.com</website> 
    </item> 
</maintag> 

EDIT：/私はKxmlparserでこの結果を解析するのに不思議に思っていました。

多くの感謝！

@Override

     super.onCreate(savedInstanceState); 

     setContentView(R.layout.main); 
     tv = (TextView)findViewById(R.id.TextView01); 

     // Maak een nieuw Soap Request object en parameter 
     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

     request.addProperty("GUID","4fe78-a4s4df8-65a4sd-465as4a"); 
     request.addProperty("InstallVersion","1"); 

     // Soapenvelope versie van webservice 
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
     envelope.dotNet = true; 

     envelope.encodingStyle = SoapSerializationEnvelope.XSD; 
     envelope.setOutputSoapObject(request); 

     // Transport gegevens vanaf URL 
     HttpTransportSE aht = new HttpTransportSE(URL); 

     try 
     { 
      aht.call(SOAP_ACTION, envelope); 
      SoapPrimitive resultsString = (SoapPrimitive)envelope.getResponse(); 
      tv.setText("Result :" + resultsString);

Javaは、XMLパーサが組み込まれています。 3つの方法のあなたが主に興味を持つだろう。ここhttps://github.com/LeifAndersen/NetCatch/blob/master/src/net/leifandersen/mobile/android/netcatch/services/RSSService.java（それはページの一番下にあります）

されています：あなたは、私はここにこれを行うために作られた最新のファイルのサンプルを見ることができます

private static Document getRSS(Context context, boolean backgroundUpdate, 
     String url) { 

    if (!Tools.checkNetworkState(context, backgroundUpdate)) 
     return null; 

    // Network is available get the document. 
    try { 
     Document doc; 
     DocumentBuilder builder = DocumentBuilderFactory.newInstance() 
     .newDocumentBuilder(); 
     DefaultHttpClient client = new DefaultHttpClient(); 
     HttpGet request = new HttpGet(url); 
     HttpResponse response = client.execute(request); 
     doc = builder.parse(response.getEntity().getContent()); 
     return doc; 
    } catch (IOException e) { 
     return null; // The network probably died, just return null 
    } catch (SAXException e) { 
     // Problem parsing the XML, log and return nothing 
     Log.e("NCRSS", "Error parsing XML", e); 
     return null; 
    } catch (Exception e) { 
     // Anything else was probably another network problem, fail silently 
     return null; 
    } 
} 

private static Show getShowFromRSS(Context context, Document feed, 
     String feedUrl) { 
    try {

Webサービスに応じて、応答はSoapPrimitiveまたはSoapObjectのいずれかになります。それのようにほとんどは、より複雑な反応であり、したがって、あなたのコード

SoapPrimitive resultsString = (SoapPrimitive)envelope.getResponse();

は、と順番にあなたからの値を持つ属性や性質を持っているこの

SoapObject response = (SoapObject)envelope.getResponse();

のようなものに置き換える必要があります応答。そこにブレークポイントを設定し、それをライブで調べるのが最も簡単かもしれません。 http://code.google.com/p/ksoap2-android/wiki/CodingTipsAndTricks
