Double-click on the tAdvancedFileOutputXML
component to open the dedicated interface or click on the three-dot button on the
Basic settings vertical tab of the Component Settings tab.

To the left of the mapping interface, under Schema
List, all of the columns retrieved from the incoming data flow are
listed (only if an input flow is connected to the tAdvancedFileOutputXML component).

To the right of the interface, define the XML structure you want to obtain as
output.

You can easily import the XML structure or create it manually, then map the input
schema columns onto each corresponding element of the XML tree.
