[Haskell-beginners] Laziness and XML parsing

[Michael Snoyman]

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.
