Xml :: Set A Variable Attribute Of A Xml Element?
Jan 28, 2010
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 am trying to get the name attribute of the first element in my XML document. Here is the extract from my xml file:
HTML Code:
<shop name="Pick n Pay">
Here is my AS3 code:
var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();
xmlLoader.load(new URLRequest("mall.xml"));
function LoadXML(e:Event):void {
[Code] .....
And this is the output that I am getting:
Code:
XML loaded
XML Output

I have a Flex XML object as follows:
private var _xmlCountries:XML =
<Countries>
<option value="AF">Afghanistan</option>
<option value="AL">Albania</option>
<option value="DZ">Algeria</option>
<option value="AO">Angola</option>
[Code]...
This object is ok, and shows up correctly in debug mode. The problem is I have a country name i.e. private var _country:String = "Angola";, and I want to get the corresponding value 'AO' from the XML object. Do you know how to do this?
I have tried loads of Livedocs examples, but cant get it to work. P.S. I am working on a HtpService & WebService driven app to display global weather conditions overlayed on a Google Maps interface. Going to make it available to the Flex community when finished.

I'm trying to publish my AIR app from Flash CS5. Publishing has been fine, until I tried to use my own icon.
In the Adobe AIR 2.5 settings, under the ICON tab, I select my icon.
Now when I publish, I get the error: application.icon is an unexpected element/attribute
Now even if I don't include the icon, I can't publish.
I've found a ton of articles on fixing the same problem re application.version is an unexpected element/attribute - but nothing on this icon prob.

Recently, whenever I open up the program I get an XML parse error in the output window that reads: *** XML Parsing Errors ***Line 4157: The name attribute was not found on the string element <string playername="" tiptext="Specifies that the gradient use the reflect sprea... Line 4164: The tipText attribute was not found on the string element <string playername="" ti`text="Lets the user drag the specified sprite." This is not specific to any .fla file, but seems to be related to Flash itself. The program seems to work fine otherwise. Can anyone shed some light on this?

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;

I'm getting some warning signs in FDT in a couple of lines of code that access values in the app descriptor, like this:
var appDescriptor:XML = NativeApplication.nativeApplication.applicationDescriptor;
var ns:Namespace = appDescriptor.namespace();
var appId:String = appDescriptor.ns::id[0];
var appVersion:String = appDescriptor.ns::versionNumber[0];
Those lines work fine, but FDT underlines "id" and "versionNumber", and issues the warning "Could not resolve variable (may be an XML element name)".

I am trying to retrieve the element I added to my UI in a different function. I am using actionscript 3. I know I can put the variable into a class variable, so it can be access anywhere in the class, but I have too many elements. Is there anyway I could access them without putting them into class variable?
Code:
public class Test extends SkinnableContainer{
// private var image:Image; <-- I try not to do this, too messy

I have a particular element from an array that I'm trying to get recognized by a variable. I am getting a #1010 error on this line:

My guess is that the url variable is reading this as null and thus I get a #2007 error whenever I click the button in question.

This is probably something very simple that I just can't seem to get to work. Basically I'm trying to use a variable to be called inside of an array instead of the actual array so a simple example would be
Code:
var people:Array = [john,tom,ann];
var selected = john;
trace(people[selected]);
I get an error everytime I try to use a variable in place of and actual element

I have XML that looks like this:
<question>
<type_elt>
<opt_out_flag />
</type_elt>
</question>
type_elt is not an element name; it might be <single>, <multiple> or something else, determined at runtime. How, given this, can I detect the presence of the opt_out_flag element?
I tried this (where xml refers to the question element):
if (xml.*.opt_out_flag) {
do_something();
}
but even in cases without opt_out_flag the above expression returns true. Obviously I'm missing something, but what is it?

i can just split it into two lines, but i'd like to know for curiosity's sake, how or if i could do it in only one.[code]i'm basically trying to take an element from an array (which is a point), normalise it, and set another variable to the resulting value, without modifying the original array element.using the code above, i get a null value returned. what could i do differently to make it work as decribed, without splitting it over multiple lines. is that possible ?

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'm using a Coldfusion Dreamweaver template with cfinclude tags. The header contains a flash movie where I'd like to pass 2 variables via a query string to load the correct image and menu button based on the variables in the ActionScript.
Example: <param name="movie" value="flash/header_v8.swf?pic=1&button=1" />
pic variable can be 1 - 3 and button variable can be 1 - 7 depending on the each pages body element id. So the logic would be something like this for my flash movie:
if body id =home, then pic=1 and button=1
if body id =about, then pic=current variable and button=2
if body id =page3, then pic=1 variable and button=3
[Code].....
What's the best way to pass these variables depending on the current page body element id?

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.

I know that there is no such function as getElementByName in Flex but I also now that you can do this["object_id"] to get the element of the application u're in.What about getting an element inside another element?I've tried making element["id"] ? But in my try-catch it always runs the "catch" part..how do I get an element inside another element just having it's id in dynamically created string form?

I have flash where there is a link for song download. And, at the bottom of the flash I've a count, loaded thorugh flash vars which should increment everytime donload button is hit. Please let me know what approach should i take to do that. can i call a Java method on donload button which will insert a row in the table and and then get the count and render it to the count variable in my flash?
May be this extremely confusing. Here is a very similar example on how it is done. This is actually very similar to what i want to do. [URL] on this link there is count below which increments you hit the download button.
