      • readHeadExcludeVersion

        public static byte[] readHeadExcludeVersion​(InputStream inputStream,
                                                    byte[] tag)
                                             throws IllegalArgumentException,
                                                    IOException
        Read input stream until the specified xml tag ends, return byte array of read data without "version" attribute from given tag.
        Parameters:
        inputStream - the underlying input stream, cannot be null
        tag - byte array presentation of xml tag, cannot be null
        Returns:
        return byte array of read data without "version" attribute from given tag, never null
        Throws:
        IllegalArgumentException - if no match is found before the read default buffer overflows occurs.
        IOException - if an I/O error occurs.
