I have really searched for this, but could find no answer, my case doesn't
seem too far from the doc and examples I have read, yet...
I am just parsing an XML file, with nested elements with xmlpullparser, and
storing the datas in an ArrayList of custom Objects.
Nearly everything's ok, but I end up with 2x too many objects at the end...
From what I have gathered till now, the problem comes from the fact that a
END_TAG event is fired every time just after the START_TAG event, then the parsing continues, and I re-encounter the same END_TAG where I should see it normally.
Here's my parsing loop :
int eventType = parser.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
String name;
switch (eventType) {
case XmlPullParser.START_DOCUMENT:
Log.i(TAG, "getLoadedXmlValues __ START_DOCUMENT");
shop = new ArrayList();
break;
case XmlPullParser.START_TAG:
name = parser.getName();
Log.i(TAG, "getLoadedXmlValues __ START_TAG name = " + name);
if (name.equalsIgnoreCase("WELCOME_TEXT")) {
waitingScreenText = parser.nextText();
currentContent = waitingScreenText;
} else if (name.equalsIgnoreCase("ARTIST")) {
//Log.i(TAG, "getLoadedXmlValues __ creating new artist object");
currentArtist = new Artist();
} else if (currentArtist != null) {
if (name.equalsIgnoreCase("NAME")) {
currentArtist.setName(parser.nextText());
currentContent = currentArtist.getName();
//Log.i(TAG, "getLoadedXmlValues __ artist object exists, setting values. NAME = " + currentArtist.getName());
} else if (name.equalsIgnoreCase("PICTURE")) {
currentArtist.setPicture(parser.nextText());
currentContent = currentArtist.getPicture();
} else if (name.equalsIgnoreCase("DESCRIPTION")) {
currentArtist.setDescription(parser.nextText());
currentContent = currentArtist.getDescription();
} else if (name.equalsIgnoreCase("TATTOOS")) {
currentTattoos = new ArrayList<>();
} else if (name.equalsIgnoreCase("TATTOO")) {
currentTattoos.add(parser.nextText());
currentContent = "adding a tattoo";
} else if (name.equalsIgnoreCase("DRAWINGS")) {
currentDrawings = new ArrayList<>();
} else if (name.equalsIgnoreCase("DRAWING")) {
currentDrawings.add(parser.nextText());
currentContent = "adding a drawing";
}
Log.i(TAG, "getLoadedXmlValues __ START_TAG content = " + currentContent);
}
case XmlPullParser.END_TAG:
name = parser.getName();
Log.i(TAG, "getLoadedXmlValues __ END_TAG name = " + name);
if (name.equalsIgnoreCase("TATTOOS")&& currentArtist !=null&& currentTattoos !=null) {
currentArtist.setTattoos(currentTattoos);
} else if (name.equalsIgnoreCase("DRAWINGS")&& currentArtist !=null&& currentDrawings !=null) {
currentArtist.setDrawings(currentDrawings);
} else if (name.equalsIgnoreCase("ARTIST")&& currentArtist !=null) {
//Log.i(TAG, "getLoadedXmlValues __ END_TAG :: add artist to shop");
shop.add(currentArtist);
}
}
Here's my xml : (I download a file from the web, then write its content
in a file on the internal storage with
builder.append(line).append("\n"); )
<?xml version="1.0" encoding="utf-8"?>

And here's a Log extract:
START_DOCUMENT
START_TAG name = datas
END_TAG name = datas
START_TAG name = DATE_CREATED_TIMESTAMP
END_TAG name = DATE_CREATED_TIMESTAMP
END_TAG name = DATE_CREATED_TIMESTAMP
START_TAG name = WAITING_SCREEN
END_TAG name = WAITING_SCREEN
START_TAG name = WELCOME_TEXT
END_TAG name = WELCOME_TEXT
END_TAG name = WAITING_SCREEN
START_TAG name = ARTISTS
END_TAG name = ARTISTS
START_TAG name = ARTIST
END_TAG name = ARTIST
START_TAG name = NAME
START_TAG content = artiste 1
END_TAG name = NAME
START_TAG name = PICTURE
[...]
As you can see, no matter if an element contains nested elements or not, the opening tag always causes both the START_TAG and the END_TAG to be fired...
I have tried to log my local xml file to check it, and it is correct, so the problem has to come from my while loop...
I am completely lost as to why it is so...
Just add break; after each case
