Android: Parsen von XML mit KSOAP

Question

Ich mache Verbindung mit meinem Web Service (SOAP) dieses xml Ergebnis, dass ich von den Web Service empfangen, wie kann ich dieses Ergebnis ohne SAX-Parser analysieren ...

<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:/Ich habe mich gefragt, dieses Ergebnis mit Kxmlparser zu analysieren, kann mir jemand sagen, wie?

Vielen Dank!

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

Java hat ein XML-Parser gebaut. Sie können eine Probe von einer aktuellen Datei sehe ich, dies zu tun gemacht hier: https://github.com/LeifAndersen/NetCatch/blob/master/src/net/leifandersen/mobile/android/netcatch/services/RSSService.java (es ist am Ende der Seite)

Hier sind die drei Methode der Sie meist interessieren:

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 { 
     // There should be one channel in the feed, get it. 
     // Also, the cast should be okay if the XML is formatted correctly 
     NodeList item = feed.getElementsByTagName("channel"); 
     Element el = (Element)item.item(0); 

     String title; 
     NodeList titleNode = el.getElementsByTagName("title"); 
     if (titleNode == null || titleNode.getLength() < 1) 
      title = context.getString(R.string.default_title); 
     else 
      title = titleNode.item(0).getFirstChild().getNodeValue(); 

     String author; 
     NodeList authorNode = el.getElementsByTagName("author"); 
     if (authorNode == null || authorNode.getLength() < 1) 
      author = context.getString(R.string.default_author); 
     else 
      author = authorNode.item(0).getFirstChild().getNodeValue(); 

     String desc; 
     NodeList descNode = el.getElementsByTagName("comments"); 
     if (descNode == null || descNode.getLength() < 1) 
      desc = context.getString(R.string.default_comments); 
     else 
      desc = descNode.item(0).getFirstChild().getNodeValue(); 

     String imageUrl; 
     NodeList imagNode = el.getElementsByTagName("image"); 
     if(imagNode != null) { 
      Element ima = (Element)imagNode.item(0); 
      if (ima != null) { 
       NodeList urlNode = ima.getElementsByTagName("url"); 
       if(urlNode == null || urlNode.getLength() < 1) 
        imageUrl = null; 
       else 
        imageUrl = 
         urlNode.item(0).getFirstChild().getNodeValue(); 
      } else 
       imageUrl = null; 
     } else 
      imageUrl = null; 

     return new Show(title, author, feedUrl, desc, imageUrl, -1, -1); 
    } catch (Exception e) { 
     // Any parse errors and we'll log and fail 
     Log.e("NCRSS", "Error parsing RSS", e); 
     return null; 
    } 
}

Answer 2

Abhängig von Ihrem Webservice erhalten Sie entweder ein SoapPrimitive oder ein SoapObject. Die meisten, wie es ist eine komplexere Reaktion und damit Ihr Code

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

sollte mit Attributen und Eigenschaften von mit den Werten haben mit so etwas wie dieses

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

die wiederum ersetzt werden, um Ihre Antwort. Es könnte am einfachsten sein, dort einfach einen Haltepunkt zu setzen und ihn live zu inspizieren.

Sie können auch in meiner Wiki-Dokumentation sehen, wie die rohe XML-Anfrage und Antwort debuggen und hier zu sehen: http://code.google.com/p/ksoap2-android/wiki/CodingTipsAndTricks
