[Haskell-cafe] hxt: How to Unpickle Multiple Adjacent Elements

4 Jan 2015

      Hi,

With xml element having DTD like following:

    <!ELEMENT entry ((art*, formula?, table?), hw, hsl?, (pr | altpr)?, (ahw, hsl?, (pr | altpr)?)*, vr?, fl?, lb*, in*, ((dx) | (cx?, def?))?, dro*, dxnl*, uro*, syns*)>

I want to unpickle the sequence

    hw, hsl?, (pr | altpr)?, (ahw, hsl?, (pr | altpr)?)*

into Haskell data type [Headword] where

    data Headword = Hw { hwText       :: String
                       , hwSl         :: Maybe String
                       , hwPr         :: Maybe Pronunciation
                       }

However in the hxt pickle API I cannot found a way to extract a sequence
of adjacent elements.  Is there any one knowing how to do it?

Thanks,

Jimmy Lu
