Re: [Haskell-cafe] regular-xmlpickler

Hi Adam, You are right. I didn't realise that I could write my own pickler without having a real parent xml node. Anyway, it works! Thanks for your help, Grant On Fri, Jul 11, 2014 at 9:14 PM, Adam Bergmark wrote:

Hi Grant,

This is an edge case since you have a field name with the same name as a constructor. regular-xmlpickler doesn't try to treat this case differently, I'm not sure if there is a good way to generically fix this in the way you want.

That said, you can always write your own picklers using plain hxt to flatten the structure, and note that you can mix custom instances with regular-xmlpickler generated ones.

Also see the hxt-pickle-utils[1] package for a few helper functions

Cheers, Adam

Hi,

I am using a very cool package called regular-xmlpickler. Does anyone know of a way to skip one level of nesting for nested complex fields? So I would like to elide that outer/inner Header.

Here is the full code: http://lpaste.net/107362

data User = User { name :: String , admin :: Bool , dt :: UTCTime , header :: Header }

data Header = Header { header1 :: String , header2 :: String }

so instead of generating <header> twice

<header> <header> <header1>abb</header1> <header2>abb</header2> </header> </header>

I would like to have it generate this.

<header> <header1>abb</header1> <header2>abb</header2> </header>

Thanks, Grant
