XMLLists as Dataprovider problem

Question

I have an XML variable "theResult" equal to the following xml
from a flickr webservice call (without data):
<rsp>
<photos>
<photo>
<tags>
<tag>here1</tag>
<tag>here2</tag>
<tag>here3</tag>
</tags>
</photo>
<photo/>
<photo/>
<photo/>
<photo/>
</photos>
</rsp>
I added the <tags> and <tag> manually. I wanted
to display this data in a TileList of VBoxes, so I set the
dataProvider of the TileList as "{theResult.photos.photo}", without
any problem. I also wanted to display each tag, so I tried setting
a Repeater in the VBox with a dataProvider of "{data.tags.tag}".
However, nothing displayed, so after much searching I discovered
that setting "{data.tags.children()}" as the dataProvider for the
Repeater would work. I just would like to know why this is so, just
to satisfy the curiosity that futile hours of work have built up.
Shouldn't data.tags.tag be an XMLList just as
theResult.photos.photo or is data found using "." notation handled
somehow differently for XMLLists than XMLs?

Answer 1

Thanks for the reply. When I set theResult your way it works
fine. However, in my code I set theResult with the following
statements:
public function handlePhotos(event:ResultEvent):void
theResult = XML(event.result);
theResult.photos.photo[0].tags.@id = "enabled";
theResult.photos.photo[0].tags.tag[0]="here1";
theResult.photos.photo[0].tags.tag[1]="here2";
theResult.photos.photo[0].tags.tag[2]="here3";
I guess data binding might only be recognizing the first
statement and ignoring the rest? Or perhaps it's that
theResult.photos.photo.tags.tag does not exist when theResult is
first changed, so flex doesn't know what to listen to for data
binding? The reason I tested my code like this is because I need to
set the tags for each photo by making a call to a flickr web
service for each one before having the data to attach. I guess I'll
need to keep using the children() method.
