AS3 :: Flex - Test Existence Of Xml Attribute?
Jan 13, 2011
What is the best method to test the existence of an attribute on an XML object in ActionScript 3 ttp://martijnvanbeek.net/weblog/40/testing_the_existance_of_an_attribute_in_xml_with_as3.html is suggesting to test using
if ( node.@test != node.@nonexistingattribute )
and I saw comments suggesting to use:
if ( node.hasOwnProperty('@test')) { // attribute qtest exists }
But in both case, tests are case sensitiveFrom the XML Specs : "XML processors should match character encoding names in a case-insensitive way" so I presume attribute name should also be match using a case-insensitive comparison.

I am reading in an XML file in AS3. I need to find out if an attribute exists on a node. I want to do something like:
if(xmlIn.attribute("id")){
foo(xmlIn.attribute("id"); // xmlIn is of type XML
}
This doesn't work however. The above if statement is always true, even if the attribute id isn't on the node.

Why does the trace in the loop below return false for every iteration, even though there ARE nodes named with 6 of the 8 possible values??? This only happens when I have a namespace. Is there some other way to check for the node values???

My Flex 3 application has some modal dialogs displayed via the PopUpManager, but there are times when I'd like other view components to know there is popup displayed. The PopUpManager doesn't have any method for actually checking the existence of popups. Is there any other way to detect this in flash/flex without writing my own global manager?
(also systemManager.popUpChildren.numChildren == 0 even when there's a modal popup)

I'm trying to test a custom Flex 4 skinnable component, using the FlexUnit UIImpersonator class. If I run my tests from a FlashBuilder Spark only project everything works fine. If I try to test from a project with the mx component set on the classpath I get a "getElementIndex not available in non Flex 4 projects" error.Can I unit test spark components in FlexUnits visual test environment while still having the mx component set on the classpath?
UIImpersonator delegates it's method calls to a "testEnvironment".The implementation used for this "testEnvironment" is decided by the VisualTest EnvironmentBuilder class and the FlexEnvironmentBuilder class. If the FlexEnvironmentBuilder class can find the "mx.core.Container" on the classpath it returns a MX environment, else a Spark environment. Only the spark environment has valid implementations for Flex 4 relevant method calls on the UIImpersonator - like the addElement method.

In FlexUnit 1 it is possible to access the name of the currently-running test using the TestCase.getName() method because all tests subclass TestCase. In FlexUnit 4, however, there's no base class for tests; the tests are identified by annotations. So, how can I replicate the getName() functionality in FlexUnit 4?

I am having trouble parsing some xml that has a few attribute names with : characters in them. The compiler is not throwing any errors and when I trace my complete xml object out it is all there, however when I try to trace out any element or node it keeps comming up undefined. I removed the attribute names with : characters in them and everything works fine. I cant seem to target the attributes either to delete them.

I need to check for file existence in Flash on x number of videos. I've tried LoadVars and MovieClipLoader. LoadVars works but it actually loaded the entire video before reporting its done. Without a way of knowing that its started, I can't delete it before its done. I don't what to load the entire video, i just want to check that its there. MovieClipLoader has onLoadError and onLoadStart, which works because I can unload the MovieClip right after its starts loading and know its there and if there's a load error I know it's not there. Should work, but I need to run that x number of times to check for the other videos.

I'm working on a simple non-XML-based slide show where the container MC dynamically loads sequentially numbered files (01.swf, 02.swf, 03.swf, etc). As you may already be gathering, I want to write a little loop that returns true if the file is there, e.g. if there's only files, 01.swf � 07.swf and the loop checks for 08.swf and doesn't find it, it returns false. BTW, in this particular case checking loader MC's _width won't work, so I need an alternative to that.

I have an array with some elements that may repeat themselves or not (this is actually because they're attributes retrieved from xml nodes, but you don't need to know that); what I want to do is: go through that array and check for elements and store them in another array according to the following condition (this is where it gets tricky): if that element does not exist in the final array yet, store it; if it does exist already, nevermind it.
I wrote this code:
//custom method for searching through array
Array.prototype.contains = function(searchValue){
for(i=0; i<this.length; i++){
if (this[i] == searchValue){
return true
[Code] .....
Trace returns lisbon, oporto, oporto, coimbra, oporto, coimbra wich means that the only element in the destinations array being prevented from getting pushed into the final array is the first element in the initial array (in this case, "lisbon")... but if it prevents the first one, how come it doesn't prevent the others, damn it?...

I have a parent.swf file that loads a child.swf. When the child.swf is running on it's own, I'd like it to do one thing, but if it has been loaded into the parent.swf. I want it do something else (i.e. change behavior). Is there a way for the child.swf to detect whether it has been loaded into a parent.swf or not?

I'm using the FLVPlayback class to play my FLV files.
If I'm trying to play a FLV file which is not existed yet then I am getting a "VideoError: 1000" with message of Unable to make connection to server or to find FLV on server.
I want to check for the FLV file existence using the file URL or path, before playing that FLV by FLVPlayback.

I wish to extract an attribute from an XMLList and assign it to a string. Here is the snippet of the XML
<node>
<sport GAME="Squash" TIME1="2" TIME2="3" TIME3="8"/>
<sport GAME="Table Tennis" TIME1="4" TIME2="6" TIME3="7"/>
</node>
I have two variables. One variable will contain the game type, either Squash or Table Tennis. The other will contain one of the following strings "TIME1", "TIME2" or "TIME3". The variables are called game and time. I have tried many variations on the code below to get the needed attribute but with no joy.
var result:String = node.sport.(@GAME == game).(attribute(time));

In ActionScript 3 you can declare optional parameters like this:function (i:int = 0, s:String = "", o:Object = null):void { }So you can check if the user passed parameters s and o because you can test against the empty string or the null object if(s && o)...But how do you allow an int to be truly optional? What if all values for i are valid, including 0, negative and positive integers? And what if you want to enforce integer (not use Number?)what's the best practice here? the (...) rest may work but then you can't enforce a certain number of parameters at runtime, nor can you make for useful code completion?

Flex has an issue with hyphens in xml. I need to generate an xml object with hyphens in the attribute for a Google Checkout implementation.
I can get away with:
var xml:XML = <item-description/>;
and
var xml:XML = <item-description the-name="foo"/>;
but what I need to do is set the value of an attribute like this:
var timestamp:String = methodToGetMyTimestampString();
var xml:XML = <item-desc/>;
xml@start-date = timestamp;
but I can't do that. Since flex doesn't like the hyphens, I don't know how to get or set attributes with hyphens in the name.

I'm trying to create a button skin, where i can set fillColors like in a Flex 3 button, using CSS. It was easy to set the color of the gradients, by reading them from the CSS: adding a few lines in updateDisplayList: fillGradient1.color = fillColors[0]; ...
How can i set the colors for the other states, from script? I tried adding fillGradient1.color.down = fillColors[2] and it's not working...

have an RSS feed, within Flex I have connected to the feed via HTTPService, the XML structure is as follows (not exact, but for the purpose of the question). I am able to walk down the xml and access the data within the title and link nodes with success but when I get the the description node and try to access the img and src attributes within it, I haven't had any success. Reading about parsing with e4x the example I get is:
var xList:XMLList = xData.channel.item.description.(attribute("src"));
or
var xList:XMLList = xData.channel.item.description.(@src);
