Reading and displaying RSS feeds in Flash MX 2004-03-11 - By Merrill, Jason

Yes.
- keeping it onlist:
:::>Nothing shows up. Is "o" not available outside the function
:::>block? Is there
:::>a way that I can make it available?
Yes, you are trying to access the o object before the XML is done loading.
Darron mentioned this earlier actually (no problem, its a lot to keep track of!
) That's why the traces in the code I posted are inside the funciton block.
You can tell flash to do whatever you want to let you know its done, like say
move the playhead to the next frame where you do your text displays. Just put
the desired command in the function block where I put the traces (after the
XMLtoObject call). Then do whatever you need to do to display the text - like
have it in frame 2 or something.
In other words, don't try and display the XML before its ready.

Yes, any node that has more than one of the same kind is made into an array, so
just check the length of the Array, like this:
howManyItems = o.rss.channel.item.length;
Since there are several "item"nodes, item is an array object. Pretty cool huh.
