One of my customers just reported a strange problem with the RegEx replace function.
A simplified version of the problem is:
Search String: (.*)
Replace expression: $1xxx$1
Input Expected Result Actual Result
c1 c1xxxc1 c1xxxc1xxx
c2 c2xxxc2 c2xxxc2xxx
c3 c3xxxc3 c3xxxc3
If we change the Search string to (.+) it works as expected.
Or we can use (\w+) also... but not (\w*).
Is the '*' somehow matching the LineEnd characters also?
But if so, that should cause it to add additional line end characters, so that can't be it.
Note that this is a very simplified version of what the customer is actually trying to do.
