I don't fully understand the question.  Do you mean that you have data
of the HaXml-defined type Text.XML.HaXml.Types.Content?  If so, then
there is no need to convert it to any instance of XmlContent, just in
order to write it to a file.  hPutXml would only convert it back again!

You can write ordinary Content data just using

    import Text.XML.HaXml.Pretty as PP
    import Text.PrettyPrint.HughesPJ (render)

    main = ( hPutStrLn h . render . PP.content ) mydata
