ActionScript 3.0 :: Way Of Parsing An XML Feed With Multiple Namespaces With?
Apr 27, 2010
I have seen the following methods to be used in several online examples, but haven't found any documentation on the recommended way of parsing an XML feed.[code]
I am totally new to actionscript (barely could set up the IDE environment for Linux). I have trouble parsing an xml file containing some namespaces. All the tutorials and samples i found online are not working for me. the file looks like this:
var myXm : XML = <feed xmlns="http://www.w3.org/2005/Atom" xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/" xmlns:georss="http://www.georss.org/georss" xmlns:thr="http://purl.org/syndication/thread/1.0">
I can get all the normal nodes of my rss parsed fine but there are a few nodes that I am having trouble with. In the code below I can pull the info from "<item>", "<title>" and "<description>" but how would I go about pulling the info from the node "<enews:url>" ? Currently to get to item I am using: xml..item[0] in my parsing of the xml to an object.
Makes sense, right? Now let's add this attribute. var xml:XML = XML(<feed xmlns="http://www.w3.org/2005/Atom"><entry /><entry /><entry /></feed>); trace(xml.entry.length()) // returns 0
Well that can't be right. Let's try it with a different attribute.
Anyone know what would cause this? I used atom as an example, but any 'xmlns' attribute on the root node seems to have this effect. The value returned is straight up false - there are obviously still 3 'entry' child nodes regardless of the attributes their parents possess.
I'm having a problem parsing a JSON file in AS3. Im trying to parse multiple JSON arrays, but don't really know how to get to the next after accessing the first one. My JSON file looks like:
{ "term": [ { "id": 4211, "place": "NEW YORK CITY" }, {"id": 2675, "place": "WASHINGTON (DC)" [Code] .....
I can get the data from the first array, but how would I structure my code so that I could iterate through 2 or more "term" arrays?
I'm new to Flex. I've been graphing multiple series in a line chart where all of these series are the same length. Now I need to plot new data and each series has a different length from each other. The question is how to modify the following code to do this.
The initApp() function is called at the start of the program, and it calls function genData() to generate the dataSet used for plotting in the LineChart.
public function initApp():void { // Initialize data provider array. dataSet = new ArrayCollection(genData());
[Code]....
Can someone recommend how to place array1, array2, array3, and array4 into x1, y1, x2, y2 (respectively) when the length of array1 and array2 do not equal that of array3 and array4? Or, equivalent outcome.
I'm assuming everything has to come in through dataSet, but I wonder if it's possible to simply reference array1 (etc.) directly from <mx:LineChart ...> or <mx:LineSeries ...> somehow, to avoid wasting memory on an unnecessary array (e.g. dataSet).
I worked on a flex application 6-7 months back. We used flex 3.5 sdk. Now we are upgrading our flex app with flex sdk 4/4.1 I am still new to flex development and I have a very basic question related to namespace. I have seen three different namespaces in flex sample applications. What is the purpose of having three diff namespaces? When do I use each of them ?
I'm trying to get data from a namespaced xml file in a flex app. There is a root namespace (xmlns="blah") and another namespace (xmlns:i="blah"), and I'm able to access most tags using the following: var ns:Namespace = doc.namespace(); var result:XMLList = doc.ns::element;
However, there are several tags that are subject to change in the application, and i'd like to not hardcode them, possibly using the elements method: var result:XMLList = doc.elements(configuredField); Is there a way to get elements with namespaces using the elements method, or a similar way to get XML elements in flex using a parameter?
I am trying to learn flex4 from adobe document and I am very confused while using three namespaces.. there is no way i can keep track of when to use what often ending up using fx inside mx or s or similarly making some stupid goofed up combinations of {fx,mx,s}.
Adobe document is huge and i am looking for some good starting point for learning flex .
I'd like to know if it's possible to store namespaces in an array?Imagine i had infinite namespaces and i'd use "for" to store them automatically, what would i need? i don't think an array would save namespaces as they are.
I'm writing some actionscript to provide a flash frontend to an MS Excel spreadsheet. The idea is that the user will be able to press buttons in a flash application, and that will enter data into the spreadsheet (which will be read and written as XML).
I have this XML object, and I need to display parts of it so that the user can copy and paste from it. However, whenever I try to, say, display the category section by doing myXML.category, it puts the namespace information in the attributes of the first <category> tag when it displays the xml. Is there a way to get rid of this?
I'm trying to compile an SWC file from a list of given ActionScript classes. I'm using the compc compiler. The problem is that there are so many classes grouped into multiple namespaces that I am finding it very tedious to specify each individual class to be included in the SWC. Is there any easier way of doing this like just simply specifying a root directory of these classes? At the moment I have something like this:
I'm trying to create a property that can be set by extending classed and read publicly.I couldn't think of a good naming convention for a protected property with a public getter, so I tried to do this:
public function get name():String{ return _name; } protected function set name(string:String):void {[code]......
However I get the error (when trying to set name in an extending class): 1178: Attempted access of inaccessible property name through a reference with static type testing:TestComponent.1059: Property is read-only.
Can methods declared with a custom namespace be overwritten?
Code: // secret.as package { public namespace secret = "http://www.example.com/secret";
[Code].....
If I try the above I get "1004: Namespace was not found or is not a compile-time constant." If I remove override I get "VerifyError: Error #1053: Illegal override of test in Extended."
1157: Interface members cannot be declared public, private, protected, or internal.
I'm just curious as to WHY? I don't understand the thinking behind this "law".
Does this perhaps mean that interface properties always need to be public when implemented in the target classes, and produces this error in order to help enforce that law?
I haven't tested if custom namespaces produce the same error. I'll delve deeper into this when I get the time.
Given this:public namespace foo;foo var bar:String = "baz";We can access the property "bar" like so:[code]It gives me the following error: ReferenceError: Error #1069: Property foo::bar not found on MyClass and there is no default value.On further inspection of the foo namespace I can see (in the debugger) that the URI is in the format {package}:{type}/{name}. If I try to replicate this by doing the following:[code]Does anyone know if it is possible to get access to namespaced members like this? I don't have compile time access to the namespace, but I can look up it's uri (and prefix) dynamically at run time.
I have the following packages.Within spark I have a class SeCore; and within spark.engine I have SeStepper and SeKeyboard.What I'm trying to achieve is have SeCore as being the only class that can create an instance of SeStepper or SeKeyboard. This can be achieved by moving SeCore into the spark.engine package and making the other two classes internal, but I'd like to have SeCore in the spark package if possible.I've tried making my own namespace to handle this, like so:
As the title says - is it possible to document my ActionScript packages / namespaces using the ASDoc comments and the included asdoc command line tool?
I'm up late coding and I've come to a halt here's why:
I'm looking (desperately) for something that will explain why my "public class marquePage" is not working properly. I don't have access to the actual file right now - on a friend's computer - but i'll try and make this clear, here it goes :
Code: // example : (having declared the namespaces at package level and embedded the pictures in separate classes "photosMP", etc) public var ceNom:Namespace; public var cetteListe:Array = [photos, dessins, livres, maous];
[Code].....
Somehow, the event listener doesn't want to know about namespaces... in fact, everything comes up ok except that when you click on any of the bookmarks (cetMP), nothing happens at all
Trying to migrate to AS 3.0 here, but are facing a tough time at kick-off: I have a base fla file located in a folder named "game". The "game" folder is in a folder named "northcreek" which again is in a folder named "no". For no other reason than that I read somewhere that this was smart. Anyway, I have in my (document) class under publish settings this: no.northcreek.game.Engine Both my "game.fla" and my "Engine.as" reside in the "game" folder, but I fail to reference my as-class from my fla file. What do I do wrong? It works if I simply remove all namespace names, and only type namespace, but I am trying to do it the right way here...
I have a couple of questions that I hope someone can answer. I have this ActionScript that reads the XML file into the flash movie. The poblem is this: The XML is in this format:
