用于编码/解码EXI的java示例？

    public static void main(String[] args) throws Exception {
        // XML数据
        String xmlData = "<root><element1>value1</element1><element2>value2</element2></root>";

        // 创建SAXParser和XMLReader
        SAXParserFactory factory = SAXParserFactory.newInstance();
        SAXParser saxParser = factory.newSAXParser();
        XMLReader xmlReader = saxParser.getXMLReader();

        // 创建EXI编码器
        EXIFactory exiFactory = DefaultEXIFactory.newInstance();

        EXIResult exiResult = new EXIResult(exiFactory);

        // 设置编码后的输出流
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        exiResult.setOutputStream(outputStream);

        // 设置XMLReader的ContentHandler为EXI编码器
        xmlReader.setContentHandler(new SAXEncoder(exiResult));

        // 解析XML数据
        xmlReader.parse(new InputSource(new ByteArrayInputStream(xmlData.getBytes())));

        // 获取编码后的EXI数据
        byte[] exiData = outputStream.toByteArray();

        // 打印编码后的EXI数据
        System.out.println("Encoded EXI data: " + new String(exiData));

        // 解码EXI数据
        // TODO: 添加解码EXI数据的示例代码
