UART with DMA and new line detection

Hi all, in my project which takes data from a device from UART, and I have made it use the DMA to save the info.  The callbacks HAL_UART_RxCpltCallback and HAL_UART_RxHalfCpltCallback are called and working well.  However, I have to detect the new line character to do some action according to the data, what is the best approach to this?  I am using STM32F051, and the UART_IT_LBD interrupt looks interesting but cannot get it to fire.

Sorry if this is a silly question, but I really do not know which direction to go at the moment.
