Xml :: Flex Tag Attribute Value / Property Parsing?
Sep 24, 2010
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);
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 have an XML file I'm parsing out into a Flash movie. The XML contains multiple nodes, and within those nodes are multiple attributes.So, for example, there is a node called FirstNode. In that is an attribute FirstNodeID="1" and then there is another node, also called FirstNode which has an attribute of FirstNodeID="2". Each node also has attributes called Header and Body and so on.
What I'm wondering is, how do I call out specific things based on an attribute?Right now, when I call the Header attribute from FirstNode I get ALL of the Header information from ALL of the FirstNode nodes. I need to be able to get JUST the info from FirstNodeID="1", FirstNodeID="2" and so on as needed.
[Code]...
I'd like to be able to be able to simply rename the dynamic text fields and then only paste in the actionscript that defines what nodes to pull the text from and what fields to put it into. So everything from the //MAIN TEXT area in the actionscript above.
<set name="thumbsBooks"> <set name="pdf"> <thumb>Data I want to access</thumb> <thumb>Data I want to access</thumb>
[code]....
I want to be able to get the data contained in the "thumb" tags using the "name" attribute value of the parent tag as a selector, something like you would do in jQuery: $('set[name="pdf"]').find('thumb');Is there a method like this in Action Script 2 (can't use AS3)?
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.
The errors are one line 123 and 128.I've googled the error, but I still can't fix it, it's got me baffled for an hour now! I've tried adding curly brace's but still same error. I left line 123 and 128 like this
function _update(e:Event):void { _helicopter.update(_mouseDown); } function onEnterFrame(e:Event):void {'
But I'm getting an error stating that _update is not defined
I keep getting this error in my class file main.as this is a translator application. I was able to get the animations working at one point but now I am stuck with this error and I don't understand it.
I have an xml file and im putting this xml file in an XML object
var receivedXML:XML
In some function, I have:
var xmlList:XMLList = new XMLList(); xmlList = receivedXML.some.attributes.here; object.functionDoStuff = xmlList;
The function functionDoStuff takes xmlList as its argument:
function functionDoStuff(xmlList:XMLList) {}
When does receivedXML get parsed, is it when we assign it to xmlList, or is it when it gets used in the next instruction by the function functionDoStuff?
In ActionScript I have string as str="subject,r1,r2:a,b:1,2:3,4"; Dynamically I have split this string and build array collection as given below arraycoll.addItem({subject:a ,r1:1,r2:3}); This example of one set. The array collection should be built dynamic. I have tried but not successful.
to use string function splice etc. to replace tags with the one which text fields can understand but is it too complex and processing over head is there that reduces the efficiency but i have max control to do changes what i needed. parsing the html to xml and then use this as the text input to text field what about the efficiency and control need to know about from this question. regular expressions .
I have done some searching around, and from what it looks like so far, there is no native way to parse JSON in Actionscript/Flex. XML is automagiaclly parsed and life is good. Why isn't JSON parsed this same way?
Setting the text property of a flex DateField makes the selectedDate property of that DateField go to null.I need to set the text property so that I can use a particular format (DD-MMM-YYYY).
Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
I have this variable in Model class:[code]I've used BindingUtils to get notified when the XML changes:[code]Function onChange gets triggered when I assign an XML to the variable, but not when I change some attribute of the XML: Model.getInstance().someXml.@attr = "newValue";
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));
Can we put [Bindable] on functions/methods? I know that bindable is used to change the value of the source property to destination property. But not sure if we can use that for methods. why we cannot put/ if we can then what will be the outcome?
i have an xml which contains 'interface' sub tag, iam converting xml to object using SampleXmlDecoder. compiler did not allow me to access the value of the 'inteface' attrible of the resultobject.
[Code]....
its treating interface as keyword. the solution for this.
I'm using a CSS file to style my flex application. can I use components IDs to change their style from the CSS file? Or I should add the styleName attribute for each element?
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...
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.
