Remove a SINGLE instance of a substring from within a string (smart values)

Chris Smith

Hi, 

    I am trying to remove a single instance of the string REM (which is a smart value) from the string TOT (which is also a smart value). Im within a branch when doing this but I dont think that the branch is the problem. So basically I want to do something like

 

Assign TOT.remove(REM) to TOT

If TOT is ABCDEFG and REM is CDE, then this works fine

But if TOT is ABCDEFGABCDEFG and REM is CDE, then I want it to only remove the first occurrence. But of course thats not the syntax of remove.

So I tried things like getting the left and right hand sides separately and then concatting

so left would be TOT.left(TOT.indexOf(REM))

and right would be TOT.right(TOT.indexOf(REM)+REM.length()) 

and so the whole thing would be 

TOT.left(TOT.indexOf(REM)).concat(TOT.right(TOT.indexOf(REM)+REM.length()))

Except this means nesting smart values, and JIRA doesnt like that (at least thats what I understand).

So does anybody have a cunning way of doing this?

You can try using String.replacefirst() (I have not tried this myself) or you can try a regular expression that accomplishes what you are looking with String.replaceAll() (which I have used). There are lots of online tools to help figure out the regex (e.g., regex101).  Hope this helps.
