Example generic XML Parser that I used to externalize configurations for an application.

XMLParse.java

        try {
            File configFile = new File(Environment.getExternalStorageDirectory().getPath() + "/Android/data/" + getPackageName() + "/config.xml");
            InputStream in = new FileInputStream(configFile);
            String ns = null;

            SharedPreferences.Editor editor = appPreferences.edit();
            //editor.clear();
            boolean prefsEmpty = false;
            if (!appPreferences.contains("pref_key_optionx")) {
                prefsEmpty = true;
            }
            String key = null;
            String value = null;
            String type = null;

            try {
                XmlPullParser parser = Xml.newPullParser();
                parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
                parser.setInput(in, null);
                parser.nextTag();

                parser.require(XmlPullParser.START_TAG, ns, "config");
                while (parser.next() != XmlPullParser.END_DOCUMENT) {
                    if (parser.getEventType() != XmlPullParser.START_TAG) {
                        continue;
                    }
                    String name = parser.getName();
                    // Starts by looking for the entry tag
                    if (name.equals("option")) {

                        key = parser.getAttributeValue(null, "key");
                        value = parser.getAttributeValue(null, "value");
                        type = parser.getAttributeValue(null, "type");

                        if (key != null & value != null) {

                            if (appPreferences.contains(key) || prefsEmpty) {

                                if (type.equals("boolean")) {

                                    editor.putBoolean(key, Boolean.parseBoolean(value));

                                } else if (type.equals("string")) {

                                    editor.putString(key, value);
                                }
                            }

                            key = null;
                            value = null;
                            type = null;
                        }

                    }
                }

            } catch (XmlPullParserException e) {

                Log.e(LOGTAG, e.getLocalizedMessage());

            } finally {

                editor.commit();
                in.close();
                configFile.delete();
            }
        } catch (FileNotFoundException e) {

            Log.e(LOGTAG, e.getLocalizedMessage());

        } catch (IOException e) {

            Log.e(LOGTAG, e.getLocalizedMessage());
        }
