Remove string, from a column, at the end of a string

Hi, I’m interested to remove, for each row, from the value in the column numeroDocumento the value contained in the column Anno, but only if it’s at the end or begin of numeroDocumento. I tried with String manipulation’s node but i’m not able to specify to remove it only if its at the end or begin and not also in the middle of the value in numeroDocumento. I attached a screenshot to make it clearer. For example in the row1 i want to change the value in numeroDocumento from 20261005800050 to 1005800050. Thanks to everyone can help :slight_smile:
