Thanks all for your help so far. Using xml-enumerator, is there any way to parse the following xml, and ignore the people tag? In other words, can I parse it by only providing an Iteratee for Person, no matter where a <person> tag appears nested within a document?
 <?xml version="1.0" encoding="utf-8"?>
 <people>
     <person age="25">Michael</person>
     <person age="2">Eliezer</person>
 </people>

Thanks for the heads-up, it's just a few minor tweaks in the 0.3->0.4
transition. I'll update later, and add a link to the blog post, and
release a new version to Hackage.

Thanks so much to both of you that sent that link.
Sorry, my email totally wasn't clear. I meant that the example in the
package description doesn't
run: http://hackage.haskell.org/packages/archive/xml-enumerator/0.4.3.1/doc/html/Text-XML-Stream-Parse.html#t:ParseSettings
I'll read through that article.

Here's a blog post on the package:
http://www.yesodweb.com/blog/2011/10/xml-enumerator . It doesn't cover
the streaming interface, but it might give you a good overview of the
package in general. I'm not sure what you mean by "it doesn't run,"
but you'll need at least a basic understanding of enumerators to get
off the ground.

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.

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,
