Hi I need some help desperatly I am trying to make a rss aggregator and i am stuck at the moment as I can seem to parse out the HTML info that is held in the certain sections of the rss document. below I have posted my AS3 code as well as the rss doc info. Could some one please advise me on how to parse out the HTML from the description and title of the rss feeds. Thanks.
[AS]import fl.controls.UIScrollBar;
var finalNote:String = “”
trace( finalNote );
var urlVar:String = “rss_example.xml”;// local XML file that loads by default
reloadRSS();// function to initially load or reload the feed
feed1.addEventListener(MouseEvent.MOUSE_DOWN , feed1Pressed );
function feed1Pressed(event:MouseEvent):void {
urlVar = “test2.rss”;
trace( finalNote );
reloadRSS();
}
feed2.addEventListener(MouseEvent.MOUSE_DOWN , feed2Pressed );
function feed2Pressed(event:MouseEvent):void {
urlVar = “test.rss”;
trace( finalNote );
reloadRSS();
}
//the main function for loading or reloading the feed
function reloadRSS() {
//arrays for storing the data from the XML file (i know we really aren’t using the pubDate data, but its stored anyway
var titleList:Array = [];
var descriptionList:Array = [];
var linkList:Array = [];
var pubDateList:Array = [];
//num for while loop later
var b:Number = 0;
// creates and adds onstage an empty sprite for each of other article templates (dynamically attached during the while loop)
var holder:Sprite = new Sprite();
addChild(holder);
// loads the XML data
var xmlURLLoader:URLLoader = new URLLoader();
var xmlURLRequest:URLRequest = new URLRequest ( urlVar ); //urlVar is the location of the feed (no longer hardcoded as string data like the first example fla)
xmlURLLoader.load( xmlURLRequest );
xmlURLLoader.addEventListener( Event.COMPLETE , dataLoaded );
//what to do once the function is loaded…
function dataLoaded(event:Event):void {
var theXMLData:XML = new XML ( xmlURLLoader.data ); //stores the data in an XML array
var a:Number = theXMLData.channel.item.length(); // var a is the number of items in the XML file (i.e. the total number of articles)
/* uncomment the following line if you want to trace what the title of the blog is (like Yahoo News, Digg, etc)
trace ( theXMLData.channel.title );
*/
while (b < a){ // loops through the following until b is no longer less than a (the total number of articles
// populates the empty arrays we setup above with the XML data
titleList.push( theXMLData.channel.item**.title );
descriptionList.push( theXMLData.channel.item**.description );
linkList.push( theXMLData.channel.item**.link );
pubDateList.push( theXMLData.channel.item**.pubDate);
with (holder) { // changes the scope of the code to the holder Sprite , (so temporarily the scope is not here in the main timeline)
var theTemplate:MovieClip = new articleTemplate(); // articleTemplate is the linkage ID in the Library , very important to copy this symbol to any .fla you want to use the reader with
theTemplate.x = 0;
theTemplate.y = b * theTemplate.height; // stacks each article on top of each other
theTemplate.titleBox.text = titleList**; // fills in the Dynamic text boxes inside the articleTemplate with the XML data
theTemplate.descriptionBox.text = descriptionList**; //ditto above
theTemplate.urlVar = linkList**; // gives the urlVar in the articleTemplate symbol the value from the XML data
addChild(theTemplate); //finally adds the articleTemplate into the holder
}
b = b + 1;
}
//sets up the scrollArea
myScroller.source = holder; // myScroller should be onstage. holder was created earlier in the code.
//sets up the dropShadow
var dropShadow:DropShadowFilter = new DropShadowFilter();
dropShadow.color = 0x000000;
dropShadow.blurX = 20;
dropShadow.blurY = 20;
dropShadow.angle = 45;
dropShadow.alpha = .5;//range of 0 to 1 (1 being 100%, 0 being 0%)
dropShadow.distance = 10;
var filtersArray:Array = new Array(dropShadow);
myScroller.filters = filtersArray;
}
