      public boolean parse(InputStream in, OutputStream xmlOut) throws IOException

      Parameters:
      in - the InputStream to search
      xmlOut - to write the XMP packet to
      Returns:
      true if XMP packet is found, false otherwise
      Throws:
      IOException - if an I/O error occurs
      TransformerException - if an error occurs while parsing the XMP packet
