Get data from XML in String - Android

Question

I'm using SOAP service to get ticket. I'm sending user and pass, and I'm getting xml in String. For this I'm using ksoap2.

@Override
protected String doInBackground(String... params) {

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    request.addProperty(USER, params[0]);
    request.addProperty(PASS, params[1]);

    SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    soapEnvelope.bodyOut = request;
    soapEnvelope.setOutputSoapObject(request);

    HttpTransportSE HttpTransport = new HttpTransportSE(URL);
    try {
        HttpTransport.call(SOAP_ACTION, soapEnvelope);
        return soapEnvelope.getResponse().toString();
    } catch (IOException | XmlPullParserException e) {
        e.printStackTrace();
        return null;
    }
}

@Override
    protected void onPostExecute(String XML) {
        super.onPostExecute(XML);
        if (result != null) {
           // Here I need to get data from XML

        }
    }

My XML String looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
<resp err="0">
<ticket>1234567989</ticket>
</resp>

So I need to get the error number, and the ticket number.

Don't convert your response to String and return it, instead get properties you need with getProperty() method and convert them to String. Here's how i was doing it:

    String ticket;

    public void getSoap() {

    SoapObject request = new SoapObject(NAMESPACE, METHODNAME);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.implicitTypes = false;
    envelope.setOutputSoapObject(request);
    HttpTransportSE httpTransportSe = new HttpTransportSE(URL);
    httpTransportSe.debug = true;
    SoapObject response = null;

    try {
        httpTransportSe.call(SOAPACTION, envelope);
        response = (SoapObject) envelope.getResponse();
        ticket = response.getProperty("ticket").toString();

    } catch (Exception e) {
        e.printStackTrace();
    }

}

Getting "err" element from attribute might require a bit more research but you can try this where you get ticket:

String err = response.getAttribute("err").toString;

Hope this helps and happy coding !
