[Haskell-cafe] xml conduit

Hi, Is there a nice way to update xml. I want to be able to use xml-conduit to find a location in the xml and then add/update that node. eg xpath from //d/e/f and then change the content at 'f' or add a new node <a> ... <d> <e> <f>some data to change </f> </e> </d> ... </a> Thanks for any help, Grant
