Re: Regular expression in iSphere Source file search

I came up with
[iI]\.[a-zA-Z]+

This works on the online tester I am using (https://regexr.com/).

When I try this in iSphere source file search no results are found although
I know that (I.) definitely exists.

The regex you listed above will only match if the period is followed
by at least one *alphabetic* character at the end, not any nonblank.

The "best" remedy for that depends on what exact regular expression
features iSphere supports. Most of the testers you'll find on-line
(like the one you linked to) support PCRE, but I am not sure iSphere
does.
