I want to parse a large xml file (2GB), without putting the whole thing into memory. It's pretty simple with a sax parser in most languages, you just stream bytes to the sax parser, and wait for sax events.

I recommend you taking a look at xml-enumerator [1] and libxml-enumerator [2]. They are the SAX parsers you know from the imperative world but much easier to write =). In particular, you don't need to rely on lazyness. Cheers, [1] http://hackage.haskell.org/package/xml-enumerator [2] http://hackage.haskell.org/package/libxml-enumerator -- Felipe.
