Re: [flexcoders] Built-in way to determine the number of XML elements
Why don't you just test the length of the matches element?
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute creationComplete=output()
mx:Script
![CDATA[
[Bindable]
private var xml1:XML = root
matches/
/root;
[Bindable]
private var xml2:XML = root
matches
match/
/matches
/root;
private function output ():void
{
r1.text =
XML(xml1.matches).child('match').length().toString();
r2.text =
XML(xml2.matches).child('match').length().toString();
}
]]
/mx:Script
mx:VBox
mx:Label text=First Result/
mx:TextInput id=r1/
mx:Label text=Second Result/
mx:TextInput id=r2/
/mx:VBox
/mx:Application

RE: [flexcoders] Built-in way to determine the number of XML elements
Daniel said but length doesn't do it without mentioning what it gave
him (Probably undefined.) I suspect the problem is that he said
match.length instead of match.length(). The length() of the matches
element would always be 1, because there is always exactly one matches
element, but the length() of the match element should give him the
number of match elements inside matches, which might be 0, 1, or
more.

length doesn'tdo it I think matches.match.length() -- not matches.match.length -- should give you the number of match tags. - Gordon From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Thompson Sent: Tuesday, November 28, 2006 12:56 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Built-in way to determine the number of XML elements I'm trying to see if a response from the server is empty.

I think matches.match.length() -- not matches.match.length -- should give you the number of match tags. Thanks Gordon. I was halfway there, having discovered length()... but was calling it on matches-- not match.
