Re: [Haskell-beginners] Laziness and XML parsing

I cannot seem to find a working example of xml-enumerator. It doesn't run: the names seem to have changed for some things, and I'm too much of a beginner to figure it out easily. http://hackage.haskell.org/packages/archive/xml-enumerator/0.4.3.1/doc/html/...

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.
