Hi Hiwa.
In case you didn’t know exactly how often the Element <Row> in the source will appear, I would try first the logical functoid to check if a value exist in the source field/element (logical existance/logical string). And if there is a value you can loop it in your destination schema. And then you will only have the <Rows> you like in the destination schema.
Or you can check with the equal functoid the existance of a value like “HH” in an element first and then you can decide to loop it or not.
