Problem with tAdvancedFileOutputXML using datatype Document

[Anonymous]

I want to merge two XML files together, so I'm using the tAdvancedFileOutputXML component with the feature to "Append the source xml file". 

My problem is that the input to the tAdvancedFileOutputXML is of datatype: Document

So I have only one item in the Schema list. How do I map this?

I think you need a tExtractXMLFields first.
