If the data is dynamic and especially fetched from the database the no. of
children may not be known. Yes if it is E4X, we can dig through the XML path
and specify it directly but there are places where looping cannot be avoided.
The sample in the specified URL has looping too...
for each (var num:XML in [EMAIL PROTECTED]) {
trace(num); // 123-123-1234
} // 789-789-7890

e4x? no looping needed
http://livedocs.adobe.com/flex/3/langref/XML.html
see this URL for some examples.
Also, if you put this data into a ArrayCollection of some sort of objects,
hopefully you use typed ones, you can use the filtering methods of
ArrayCollection class.

Subject: [AFFUG Discuss] Selective Data in a Data Grid
I'm grabbing data from an XML file and am wanting to only display certain nodes
in a Datagrid based on a particular value of the XML Node.
I've converted the XML over to an ArrayCollection so I can access particular
properties of the XML node, I'm just having problems excluding data from it.
I'm working on a way to change around the XML (dynamically created from a
Database) to see if I can do some array manipulation as a work around, but it'd
be nice if I could just exclude it.
So, for instance, if I had the following XML:
<FAQS>
<FAQ id="1" isHeader="1" question="About Flex" answer="" />
<FAQ id="2" isHeader="0" question="What is the Purpose?" answer="To be
awesome" />
<FAQ id="3" isHeader="0" question="Who should use it?" answer="Everyone!" />
<FAQ id="4" isHeader="1" question="About Chattanooga" answer="" />
<FAQ id="5" isHeader="1" question="About the Mets" answer="" />
<FAQ id="6" isHeader="1" question="About Donkeys" answer="" />
<FAQ id="7" isHeader="1" question="About Penguins" answer="" />
</FAQS>
>From that XML file, I only want to display the nodes that have a "isHeader"
>value of 0.
Thanks!
