Delete last occurence of a substring

Hey, how can i delete the last occurence of a substring in another string?


Input 1: test,

Output 1: test


Input 2: a,b,

Output 2: a,b

Thank you!


Hi New2Knime,


You can use a String Manipulation node with two options: 

1. Use the substr function: substr($String$, 0, length($String$)-1)

2. Use the regexReplace function: regexReplace($String$, "\\,$", "")


Please find attached a sample workflow.
