asked on

use regular expression to find data and so it can be marked for redaction

Data to be found and marked for redaction looks like this:

I50name initial. name, 0000

I50mr. name name, jr., 1111

data to be marked should be the last 4 digits

every line will end with 4 digits

i am having trouble trying to account for data that may or may not be in all lines that i am trying to find that start with I50 and end with 4 digits

The above Regex breaks down as follows:

^ = start from the beginning of the string
I50 = look for exactly this string pattern
.* = look for any character, any number of times
\d{4} = look for exactly 4 numeric digits
$ = end of the string

Basically this will match any string that starts with "I50" and ends with 4 numeric digits.

Consider using Expresso for Regex stuff. It's free but you have to register. I use it all the time and it makes life so much easier.
