See the PRETTY_PRINT keyword on the IDLffXMLDOMDocument::Save method.

As the error message suggests, you're trying to add a child node in a way
that does not make sense in XML.

For example, a Document cannot have more than one Element as a direct
child, since there can be only one top-level Element in a Document. You
didn't say what types of nodes you are adding to the Document, so we can't
tell exactly what's wrong. But, I'd guess you are trying to add more than
one Element to the Document. Note that the IDLffXMLDOMDocument object has
a GetDocumentElement method that fetches the one Element that can be a
direct child of the Document.

You probably want to make a top-level Element, and then add other Elements
to that top-level Element as children.
