How would I get the name of the attribute/varialbe at runtime? For example if I have a variable defined like
var abc:String = '123'; From this, I would like to get the variable name, which is 'abc'.
How can we change the attribute name ows_Attachments to Attachments in runtime ??
ActionScript Code:
<rootNode>
<data>
<row ows_Attachments="0" ows_LinkTitle="1" ows_productNo="1" ows_purchaseDate="2010-06-09 00:00:00" xmlns="#RowsetSchema"/>

How do you set a variable attribute of a xml element?This is what I expected to work:xmlElement.attribute(variableAttr) = "the variable attribute is set to this string";
However, I'm getting some error that this value can only be retrieved as a reference and not set.Ofcourse, the following does not work either as it will look for the attribute named "variableAttr" and not for the attribute named after the value of the variable variableAttr:
xmlElement.@variableAttr = "example";
I have an XML file loaded at run time.Among others, it contains several nodes which contain a name attribute and a value attribute.I want to be able to select name by value and vice versa.If I try and trace out a name by selecting its value, I get exactly what I expected:
[AS]
trace( "NAME: " + SiteModel.instance.constants.(@value==section).@na me );
[/AS]
But, and this is what I've been screaming at for most of the morning,if I try and assign that name to a variable, and trace the variable, I get epic fail:
[AS]
var n:String = SiteModel.instance.constants.(@value==section).@na me;
trace( "NAME: " + n );
[/AS]
Trying to trace that variable results in a TypeError:
Code:
TypeError: Error #1010: A term is undefined and has no properties.This is stupifyingly ridiculous in my opinion,
Using e4x in flex:
var attr : String = "foo";
var xml : XML =
<resultSet>
<node foo="1"/>
</resultSet>;
How can I use the variable "attr" to access
xml.node.@foo
I thought I could do it with
xml.node.@[attr]
But this doesn't seem to work. How can I access this attribute by a dynamic value like this?
Both
xml.node.@[attr];
and
xml.node.attribute(attr);
work, as Constantiner suggested.
Updates:
Say I have an XMLList in this form:
var bar:XML =
<resultSet>
<node>value</node>
</resultSet>;
I want to filter the original xml above by matching "foo" attributes with the "value" from node in bar.
Essentially I want a sublist of the original xml such that
xml.node.@foo == bar.value
for each xml row in the original value
As Constantiner mentioned, I can filter the original list by the value in foo, but what if I want to filter on multiple values?
Can I do something like:
xml.node.(bar.node.contains(attribute(foo)) ? attribute(foo) : null);
Or perhaps a cleaner method instead of the null?

I'm working on a stand-alone application and NOT a web-based application, so I'm trying to do this strictly with AS3, if possible. For example, if I have an XML file that looks like this:
Code:
<profile>
<username>Joe</username>
<password>Smith</password>
</profile>
How do I change the value of the USERNAME attribute via AS3?
I've tried something like this already:
var xmlData:XML();
...
xmlData = XML(event.target.data);
xmlData.profile.username = "Mary";
but when I open the XML file, it's not writing "Mary" in place of "Joe."
I have a flex app where I need to be able to access and modify component attributes using variable names.
eg, say I want to edit the text attributes of text label.
I am not sure what object or attribute will need to be updated until runtime.
Say I get passed the following variables:
var objId:String = "label1";
var objAtt:String = "text";
var objVal:String = "Hello World";
I need to take these and update the "text" property of label that has the ID "label1" to "Hello World".
I have tried different variations to accomplish this but am stuck One example is
this[objId][objAtt] = objVal;
what is the difference between these
var
public var
private var
im trying to do something for a scroller im working on (got it from somewhere) (trying to adjust to fit my project.the one thing thats killing me is that....a variable is set on runtime of the script,its set to receive any data

i then define what i want in there....and it doesn work...im at my wits end...and im wondering what the diff between all these vars are.
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 am trying to use the "define" mxmlc compiler option to embed compile-time constants into my SWF files.
<mxmlc ...>
<define name="NAMES::PluginCompileTime" value="Hello World!"/>
</mxmlc>
I can access this variable if I "hardcode" it into my codebase, as so: public static const PLUGIN_COMPILED_TIME:String = NAMES::PluginCompileTime; However, I would like to be able to do this at runtime using something like getDefinitionByName(): var value:* = flash.utils.getDefinitionByName("NAMES::PluginCompileTime"); This throws the following error: ReferenceError: Error #1065: Variable PluginCompileTime is not defined. Does anyone know of a way to accomplish loading a compile-time constant in a namespace at runtime?

I want to use the Event metadata tags to show what types of event my control will dispatch. The syntax looks like:
<fx:Metadata>
[Event(name="eventName", type="MyEvent")]
</fx:Metadata>
It seems like a best practice in Flex/Actionscript to define static variables that define event names like so:
public class MyEvent extends Event
{
public static const EVENT_NAME:String = "eventName";
// Other stuff..
}
It's a great practice since the event name can change easily and not have to be modified throughout the code. So my question is: Is there any way to use this static const in my metadata event tag? I can't seem to do something like this:
<fx:Metadata>
[Event(name="{MyEvent.EVENT_NAME}", type="MyEvent")]
</fx:Metadata>
Am I just ignorant of the proper syntax to do this, or is it impossible? Seems like it's just asking for hard to find bugs if someone decides to change the const since it is not strongly typed here.
Ok, I need some help on this one. I upgraded from Flash Builder 4 to Flash Builder 4.5 and have switched my project to the 4.5.1 sdk. I use an ant script to build my project, so I modified it to use the appropriate flexTasks.jar, mxmlc, etc...

I've seen the Loom project, but are there any alternatives that are more mature (and actively developed)? I am looking for something that would allow load-time weaving of pointcuts into existing binary code at runtime with the AVM2 runtime.
Has any work been done in this area?
I've been into coding for about 5 years now, but I'm a recent convert to Flash development. One of the questions I have at the moment is, considering that SWF files can be run by either Adobe Flash Player OR Adobe AIR, what's the real difference between the two runtime environments? What API's and Objects exist in one environment, but not the other?
Basically what I'm more or less trying to establish is, when would I want to develop an SWF for AIR, and when would I want to develop for Flash Player, considering that Flash Player can also execute locally (providing support for creating "desktop applications")
I have been trying to figure out how you could add in custom attribute tags that flash can recover.
EX:
<param name = "movie" value = "somefile.swf">
<embed src = "somefile.swf" width = "550" height = "400">
Except, that I would like to add a Custom tag, like "randNum" so that the tag user could input some number, or rather, a flash movie could generate a tag with a number already put in...Basically, heres a really basic version of the idea.There is a Flash Movie.In the movie, you can input text into a textfield.Upon finishing your message, you click a button "save".
The flash movie then:
1. Comes up with a random number unique to the message.
2. Assigns that number to a variable... "randNum".
3. Saves message as a xml file to the server as "filename" + randNum.
4. Outputs into a textfield a generated HTML tag that a user can post on myspace and such so that it will load in the flash movie.
Except... in the tag, there will be a custom attribute. If the random number variable "randNum" was 00112233, the custom attribute will be 00112233.
EX:
<embed src = "somefile.swf" width = "550" height = "400" randNum = "00112233">
So when the movie opens, it retrieves that randNum from the tag and can use it inside flash. How can this be done? Sorry this post was so long, but I wanted everyone to understand the concept.
Whenever I link a set of movieclips together with the bone tool which are inside a containing movieclip, and also set the type to "runtime" instead of "authortime", I get this error when published.
"Runtime symbols with skewed matrices should be wrapped in a movie clip" What does it mean? I need the type to be set to runtime so I can use scripting with it..

I'm updating an old AS2 project and have a question about XML. This thing I'm working on uses two xml files, pics.xml and lang.xml. The last one of the two contains translations for the flash file and looks like this:
PHP Code:
<lang> <trans lang="sv"> <nextPic>N�sta bild</nextPic> <prevPic>F�reg�ende bild</prevPic> <showMap>Visa karta</showMap> </trans> <trans lang="en"> <nextPic>Next picture</nextPic> <prevPic>Previous picture</prevPic> <showMap>Show Map</showMap> </trans></lang>
and in the pics.xml you choose what language to display by setting an xml attribute to either "sv" or "en".My question is, how do I tell the function that parses lang.xml to only parse the node with the right language. If "sv" is set in pics.xml I only want to parse the first bit om lang.xml there, you se what I mean? I don't what to use something like: this.firstChild.childNodes[0].blahblah cos most likely the users of this will ad more languages...
