How do I create a HaXml filter that adds a new element as a child of an existing element. For example, let's say I have the XML document: <a> <b/> <c/> </a> How do I add a new element under <a /> so that I have the document: <a> <newElement/> <b/> <c/> </a>
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 Regards, Malcolm
