Using the combinators, it goes something like this:
mkElem "a" [ mkElem "newElement" []
, children ] `o` tag "a"
Having matched the outer tag, you then rebuild it with some extra stuff
added. Obviously you would abstract the common pattern if you do this
frequently:
insertAtStart :: String -> String -> CFilter
insertAtStart outer newelem =
mkElem outer [ mkElem newElem []
, children ] `o` tag outer
