How to parse JSON from a file with BaseX?

问题

Writing a JSONObject to file file from Twitter4J seems to work, at least the file looks correct when opened manually:

public void writeJsonToFile(String fileName) throws FileNotFoundException, UnsupportedEncodingException, IOException {
    FileOutputStream fileOutputStream = null;
    OutputStreamWriter outputStreamWriter = null;
    BufferedWriter bufferedWriter = null;
    fileOutputStream = new FileOutputStream(fileName);
    outputStreamWriter = new OutputStreamWriter(fileOutputStream, "UTF-8");
    bufferedWriter = new BufferedWriter(outputStreamWriter);
    bufferedWriter.write(tweets.toString());
    bufferedWriter.close();
    outputStreamWriter.close();
    fileOutputStream.close();
}

but once the file is loaded into BaseX, or at least its JsonParser, how is the content actually parsed or processed? Must it not be converted to XML with the parser?

private void parseJsonFile(String fileName) throws IOException {
    JsonParser jsonParser = new JsonParser(new IOFile(fileName), new MainOptions());
}
