Help Changing RegEx to return a range of numbers

Currently, this expression "I ([a-zA-z]\d]{3} "

returns when the following pattern is executed:

I AAA 
I Z99

I need to change this so that it returns a range of alphanumeric characters after i from 2 to 13 that have no space.

Example:

I AAA 
I A321 
I ASHG310310

Thank,

Dave

Without quotes:



"I ([a-zA-Z \ d] {2,13})"

The parentheses {} allow you to separate a comma between two parameters, which indicates the minimum and maximum number of repetitions. Also, I'm not sure if your original regex gets what you intend - as written, it takes 3 letter groups and a number.

You might want to try



I ([a-zA-Z]|\d){2,13}
