Thanks for your answer, thols
I have a problem with your solution : the function "Research an expression" waits for a string but my file XML is a table of strings, so the types of data aren't compatible...
However, i found another solution after lots of tests :
File XML --> Function "length of a table" --> length -1 --> Function "To Index a table" with index 'length-1' for the last line, the output of "To Index a table" is the data that i have to save...
Thanks again :thumbup:
