Reading and displaying RSS feeds in Flash MX 2004-03-12 - By BRYAN MASON
Back
Jason,
Actually, I am proud to say that I did figure that out for myself finally
yesterday! What I did was to put a function call at the end of the
XML.onLoad function that takes care of displaying the desired item attribute
in the text field. Now, all I have to do is to polish it up a bit and upload
it to my web server!
I love lists like this. You guys have been extremely helpful and patient and
I really appreciate it!
One last question. Can I determine the number of <item>'s in the object by
doing something like this:
var i;
i = o.length
??
Thanks again!
Bryan

Yes.
- keeping it onlist:
:::>Nothing shows up. Is "o" not available outside the function

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.
