It looks like the function 'xmlParse' returns a value of type 'Document Posn', according to the API docs. I'm guessing the 'Posn' value is used to annotate the position in the source document a particular piece of XML came from, so you can report errors better.
Since the pretty-printing functions ignore it, you can replace it with whatever you want, even with a value of a different type if you have a need to annotate the tree.
Thanks, I was able to get it working after a little sleep/coffee. The migration guide says to replace all of the 'i' with () if you don't care about them, so I tried that, but it doesn't work in this case: the two 'i' in (CElem (Element i) i) have to match. The only way I see to construct a Posn is with noPos, so I stuck that in there. It's probably not correct, but it compiles and runs, so it's correct =)
