not sure how to add those lines into the code ...

    String line = inBuf.readLine();

   while (line != null) {
       // process line
       ...
       // read next line
       line = inBuf.readLine();
    }
}

Save the separator string (sep) then as each line is read compare it to sep and to sep+"--". If the line matches the separator then it's the start of a new part, sep+"--" then it's the end of the last part, otherwise it's exported.
