Loading an xml file into a Karabo Hash

The next code example shows how to use loadFromFile to load the content of an XML file into a Karabo Hash:

try {

    // We assume the file is inside the Karabo installation
    std::string file_name_path(karabo::util::Version::getPathToKaraboInstallation() + "/var/data/my_file.xml");

    // Load the content of the file into 'config'.
    // This is protected in a try-catch block, in case something is wrong (the file format can be
    // corrupt, for instance)
    Hash config;
    loadFromFile(config, file_name_path);

} catch (std::exception& e) {
    KARABO_LOG_FRAMEWORK_WARN << "Failed to load File: " << file_path << " : " << e.what();
}
