Xmlpullparser - Get Data From Tag With Specific Attributevalue

I'm currently creating a parser for an XML-file and everything works fine until I add an extra option to retrieve a link. I have several tags of the same name and I want one specif

Solution 1:

Without the full stacktrace its hard to point the mistake. However the below works.

publicclassXMLPullParserHandler{

    private String text;

    public XMLPullParserHandler() {

    }
    publicVoid parse(InputStream is) { // pas the input stream
        XmlPullParserFactory factory = null;
        XmlPullParser parser = null;
        try {
            factory = XmlPullParserFactory.newInstance();
            factory.setNamespaceAware(true);
            parser = factory.newPullParser();

            parser.setInput(is, null);
            boolean check =false;

           //factory instantiates an object

            int eventType = parser.getEventType();
            while (eventType != XmlPullParser.END_DOCUMENT) {
                String tagname = parser.getName();
                switch (eventType) {
                case XmlPullParser.START_TAG:
                    if (tagname.equalsIgnoreCase("image")) {

                        if(parser.getAttributeValue(null, "size").equals("extralarge"))
                        {
                            check=true;
                        }

                    }


                    break;

                case XmlPullParser.TEXT:
                    text = parser.getText();
                    break;

                case XmlPullParser.END_TAG:
                          String val = null; 
                         if  (tagname.equalsIgnoreCase("name")) {

                             val=text;
                             Log.i(""," name is "+val);

                         } 
                         elseif (tagname.equalsIgnoreCase("mbid")) 
                         {

                             val=text;
                             Log.i(""," mbid is "+val);

                          } 
                         elseif (tagname.equalsIgnoreCase("url")) 
                         {

                             val=text;
                             Log.i(""," url is "+val);

                          } 
                         elseif (tagname.equalsIgnoreCase("image")) 
                         {

                             val=text;
                             if(check == true)
                             Log.i(""," image is "+val);

                          } 

                    break;

                default:
                    break;
                }
                eventType = parser.next();
            }

        } catch (XmlPullParserException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        returnnull;
    }
}
