Extract (parse) amount and description from BIZ (Transaction) sms

Question

I am doing below steps.

1. match sms with regex

2. if contains specified keyword then get values from sms body like amount,description (reason

Answer 1

The following two regular expressions helped in finding amount from most of the bank transactions(HDFC, ICICI, ING, KOTAK, SBI, CANARA, PNB):

[Ii][Nn][Rr](\\s*.\\s*\\d*)
[rR][sS](\\s*.\\s*\\d*)

Please comment if you have figured out much better expressions than the above.
