Solution

  • Here's how you can do it :

    enter image description here

    First, iterate on your rows, and for each row read the xml column and extract the fields you want from it using tExtractXMLField. Then inside the tMap retrieve the ID of the current row that was set by tFlowToIterate.

    And the result :

    .---+----+----.
|  tLogRow_1  |
|=--+----+---=|
|id |year|data|
|=--+----+---=|
|100|2018|110 |
|100|2019|200 |
'---+----+----'
