Dear all,
I'm using Nintex Forms 2013 and the replace() function gives me some troubles.
I get a string like this, from an people picker field:
XXXXXX|YYYYYY|StringOfInterest
Where the length of the "XXXXXX" and "YYYYYY" substrings (at least to my knowledge) are not known. I want to extract the substring "StringOfInterest", i.e. replacing "XXXXXX|YYYYYY|" with "". I am using the expression (.*|){2} , which does exactly what i want to, when i enter it on https://regexr.com/ , but if i use it in the replace function in a calculated field like so:
replace(PeoplePicker,"(.*|){2}","")
i always get an empty string (yes, PeoplePicker has a value in it).
If i use something like this:
replace(PeoplePicker,"(.*|){2}","k")
i get the output:
k
,which implies that the expression matches, but disregards the umatched part of the source String. This sounds to me like a thing that the replace function shouldn't do, or did i misunderstand the replace function?
It would be nice if someone could shine a light on my lack of knowledge.
