-this text file has specific starting and end delimeters which shows the start and end of orders for each customer.
-i need to loop through this file for every customer order and create a separte pdf file from this data.
-these pdf files will be saved by customer reference number.

Any body can give me some idea how I will start this task, as I have some grey area in my mind that how I can generate these pdf files from .txt file.
