new to as4, trying to figure out how to filter xml by its child node's attribute. Something like the following. [code[The goal is to get a list of LEVEL1 and LEVEL2 that contain SAMPLE with class ="C1". Something like the following as a resulting XMLList.[code]
View 2 Repliesjust trying to get straight how this works. Say I create some XML like so:
ActionScript Code:
var sample:XML = <sample>
<items>
[code]......
I am trying to come up with the best xml schema to support tag filtering. And then a method to filter the xml on an arbritary amount of tags. So here is the xml:
var videoXML:XML=
<?xml version="1.0" encoding="UTF-8"?>
<videos>
[Code].....
I've used a lot of XML in Flash, but this one really bugs me and I can't find how to make it work!
I have a simple XML like this one:
Code:
<root>
<project>
<descr>some text</descr>
[Code]....
I can target the items (there are more in my complete xml) with: project.items.children( )But I can't seem to get to the attributes
I use this code in as3 in order to find node with specific id value but it is working for 2 depth
elementsToDraw = elementsList.*.(@id=="hello");
For example at this xml node can be found
<nodes>
<node id="d">
<node id="hello">
[Code]....
What should I write for searching in any depth element with id="hello"?
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.
My main problem with this code is I want to put the url of the image and thumbnail xml tag in the nod, instead of it being an attribute. Now I can do this easily in XML, but reading this in .as is another issue. I have attached the code below so you can see what I am doing.The files are also attached for you to see the actual code..
Code:
-----------------XML Code - below is how the image and thumbnail node's are working now... I want to get rid of the imageurl and thumburl attribute
[code]........
can I somehow word something like this:
ActionScript Code:
var i:uint = 2;
myLoader.load(new URLRequest(myXML.category[0].project[/* ...node which attribute named
[code]....
I know I can use the XMLdocument class and go back tothe old way of doing thinsg. So I have an AS3 Air app which is successfully reading and writing to an XML file. Now I want to replace an attribute or an entire node if that's easier but I can't figure out how to target it. So the XML starts with an empty node:
[code]....
What I want to know is how to target the status node (or any other node for that matter) so that I can replace it or it's attribute. So, let's say I have a bunch of these guest nodes and I want to change the status for the first one, how do I do that using the new syntax.
How simple it would be to sort some xml in order by attribute or node inside Flash, rather than reloading the data? Had a look at the class and I couldn't see anything there that would do the job.
View 1 RepliesI have a series of XML nodes that are the same (except for the data of course). I want to find the node with that attribute and use that node's data. I know I can do this with a for loop and an if statement but I was hoping that there was a better way.[code]...
View 2 RepliesI've been trying to figure out how to display the descendants (in this case exchangeRate and PlacesOfInterest) of a parent node with a specific attribute.To set the scene - the user clicks on a button which sets a string variable to a destination eg. japan or australia.The code then runs through a set of nodes in the XML and any that have a matching attribute is traced - simple enoughWhat I can't figure out is how to then display only the child nodes of the node with that attribute.I'm sure there has to be a way of doing it and I'll probably be banging my head against the desk when I find it
public function ParseDestinations(destinationInput:XML):void
{
var destAttributes:XMLList = destinationInput.adventure.destination.attributes();
[code].....
I'd like to change icon of the node according to the attribute automatically/dynamically in Flex.[code]
View 1 RepliesI have a window with a tree (each node is a category). I have a dataprovider what contains picture url and category. My goal is to filter the view with only selected node. Several nodes may be selected in the time.
View 1 RepliesI'm currently modifying an xml menu found in the kirupa tutorials and Ive gotten stuck. I want the menu to filter into different columns depending on a xml node called type="". So far I have this but I cant seem to get my head around how to filter the menu.
Code:
GenerateMenu = function (container, name, x, y, depth, node_xml) {
var currNode;
var currItem;
var currMenu = container.createEmptyMovieClip(name, depth);
[code]....
at the moment all I've tried to do is filter the menu with an if statement to only display the type node with "web" in them. As soon as I undestand how this is done I sohuld be albe to do the rest myself.
I'm trying to push just the contents of the "txt" attribute in each "question" tag into an array named "questions" in AS3 Flash. Here is an excerpt from my xml file.

I'm trying to figure out how to reference a child of an xmlList object using it's attribute value. I've successfully created an xmlList (galleries) of all the 'gallery' nodes in the loaded xml file. What I can't figure out is how to properly reference it's children when creating a new xmlList (currentGallery). What is the correct way to reference a child of the galleries xmlList by it's 'name' attribute?
ActionScript Code:
var xml:XML = new XML(loader.data);
xml.ignoreWhite = true;
var galleries:XMLList = xml.gallery;
//how could I choose to target the gallery node with the name attribute of LANDSCAPES?
var currentGallery:XMLList = galleries.gallery name=="LANDSCAPES".image;
[Code]...
Here is an excerpt of my XML file. (It is properly formatted, and has a root node, etc., but is too long to post the entire thing. Below is just the part I am concerned with.
<question id='Q1' uId='99036' no_ans='2' txt='In a flat structure employees are not expected to provide their bosses with their opinions.' feedback='' type='MC' passingWeight='1' url='media/'>
<answer id='Q1A1' uId='311288' txt='True' weight='0'/>[code]...
What I now need is a way to grab the txt attribute value from the answer tags and be able to access them from anywhere in the fla. Keep in mind that there are two answers for every question. ie:
< answer id='Q1A1' uId='311288' txt='True' weight='0'/ >
< answer id='Q1A2' uId='311289' txt='False' weight='1'/ >
How do you get the value of a child node in an array titled "entries"? I used to do this in AS2, and now I'm trying in AS3. To top it off, I'm forced to use an XML format I'm unfamiliar with. So I'm not sure how to access these nodes in AS3. An example of the XML is;
[Code]....
I have this type of XML -
<leadareas>
<pho>
<phoName>NWPHO</phoName>
<csName>nw_btn</csName>
[code]...
I would like to write a function where for example phoTit1 is returned where csname = ne_btn, but dont know if this is possible?
I have a Movie Clip called panel that I have added three children to (points, answer, question). I need to know how to access the alpha property of each child so that on a ClickEvent I can change the alpha so that the appropriate one is showing.[code]
View 8 RepliesI am trying to create a text node within a child node:
user_xml.firstChild.appendChild( user_xml.createTextNode("<![CDATA[------]]>") );
But when I trace this I get:
user_xml = <UserDetails><![CDATA[------]]></UserDetails>
Which is not what I need. What I need returning is:
user_xml = <UserDetails><![CDATA[------]]></UserDetails>
I'm trying to attach a new movie for each child node.I'm trying to add a thumbnail, description and a link to a .flv that I can load to a movie player.
Here is the code:
Code:
var video_xml = new XML();
video_xml.load("video.xml");
video_xml.ignoreWhite = true;
[code]....
When I preview the movie an empty container appears with none of the xml data.
How can I filter a loaded xml to only do my actions depending on if a xml child matches my request?

You'll see in the third once there is no link. Apparently, when I throw it into an XMLList, it gets ignored and all of the links are off by one.
I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />
I looked at the following example in the AS3 Reference: [URL] It is unclear to me looking at the package example how to apply this in standard ActionScript 3 without packages to a Movie Clip resident in my Library that gets called at RunTime. how I would push the DropShadow filter onto my Movie Clip at RunTime?
View 6 RepliesTo achieve a zoom effect in our 2D flash game, we make the background of the game much bigger than the visible stage. This becomes a problem when the background is complex or when we apply a grayscale filter to the background. Is there a better way to do zoom? Or, is there a way to apply the filter to only a specific area of a movieclip?
View 2 RepliesI 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.
