Load xml keys and values into a Map:

    public static Map<String, String> parseConfig() throws ConfigurationException {

        XMLConfiguration config = new XMLConfiguration("config.xml");
        NodeList list = config.getDocument().getElementsByTagName("entry");

        Map<String, String> map = new HashMap<String, String>();
        for (int i = 0; i < list.getLength(); i++) {
            Node node = list.item(i);
            String key = node.getAttributes().getNamedItem("key").getTextContent();
            String val = node.getTextContent();
            map.put(key, val);
        }
        System.out.println(map);
        return map;
    }

OUTPUT:
{favoriteSeason=summer, favoriteFruit=pomegranate, favoriteDay=today}

Answer 2

Just use the config.getRootNode() and then node.getChildren("entry")

XMLConfiguration config = new XMLConfiguration("_config.xml");
Map<String, String> configMap = new HashMap<String, String>();
ConfigurationNode node = config.getRootNode();
for (ConfigurationNode c : node.getChildren("entry"))
{
    String key = (String)c.getAttribute(0).getValue();
    String value = (String)c.getValue();
    configMap.put(key, value);
}

Then you can just do:

System.out.println(configMap.get("favoriteSeason")); // prints: summer
