Can you describe how this compares to HaXml? Were there deficiencies in HaXml?

The main difference is that it's simpler. It's perhaps 10-20% the size of HaXml. For a program that just has to do simple XML processing, it's sometimes undesirable to have to link in a library that does a lot more than you need.

It would be convenient to have a list of unsupported XML features. The ones I've noticed so far are

* doctypes (and all doctype-related markup) * processing instructions * notations

Comments are recognized but not preserved, so you can't round-trip a document containing them.

(Personally, I use namespaces more than I use any of these, which is why I don't use HaXml.)

I've created a wiki page to start on community documentation for the light xml library, http://haskell.org/haskellwiki/XML_Light Feel free to add text, examples, etc there -- Don
