Really only a good example on why you should use available modules. This is a Chatterbox "nodelet", much like the one you can see in the fullpage chat. It uses LWP::Simple to fetch the XML, XML::Simple to parse the content and CGI.pm to present the result.
It does not handle the [something] type links, but that should be possible to add with not too much trouble. Otherwise it pretty much mimicks the standard behaviour, and it does not add random whitespace here and there (what I've noted so far). :)
All written in a very short time, courtesy of the really cool people that write excellent modules and then distribute them. Which was what I wanted to show. :)
As usual, there is a place to take a test spin.
Update: Fixed stupid /me display bug.
Update 2: Changed title to something less confusing, as per request.
Update 3: Lots of thanks to wil for noticing that I had a forcearray bug and pointed this out to me. The code has now been updated with wil's suggestion.
