In these days I parse some RSS feeds in Actionscript 3, when I tried with E4X in Flash CS4 I can’t retrieve data in the nodes and attributes, in particular in an ATOM feed.

So I start to take a look around in the web and I find an Adobe library, made by Mike Chambers, that allow you to parse all kinds of feeds: RSS 1.0, 2.0 and ATOM.
When I tried to use it on my project, library gives me some problem because it is for Flex and not for Flash, so I modify a couple of import packages and few lines of code and now everything is ok.
In the zip file you can find an easy sample to work with this library and ATOM. 

I think it is helpful to put this modify packages for Flash downloadable from this blog, for everyone that it will find the same problem during a project.
You can find more info and documentations at googlecode page of this library project.
