[Haskell-cafe] Fwd: Stack Overflow with HaXml

[Samuel Silva]

Hello

I presents a small case studie, when I was using HaXml with DtdToHaskell.

I write small DTD:
> <!ELEMENT top (#PCDATA|child)* >
> <!ELEMENT child (#PCDATA) >

I run DtdToHaskell small.DTD > Extsubext.hs
and test it with small XML
> <top><child></child></top>

Result it is presented below:
>$ ghci Extsubset.hs
