/**
 * This class represents the XMLParser. The reason
 * I don't test it directly, is that I don't want to 
 * make multiple requests to the nominatim-server,
 * IF the tests would fail (since that would contradict 
 * to the usage policy). This class is built in
 * the same way, but doesn't process any XML documents.
