Items Tag › Brendon Smith AKA SeaCloud9 Design

Well I have been working with ActionScript3 and come across a few gotchas. Here is my conundrum. Yes it is the infamous TypeError: Error #1085: This error occurs when an html tag is not closed properly. I have been using Yahoo Pipes and combining it with flash for fun and most of the time with good results. Unfortunately when you run into error #1085 everything stops or if the html is not correctly formatted even if you wrap it in a CDATA tag nothing appears. So that kind of sucks. I will look into creating a class that analyzes the string and corrects the issue but it may not even be possible to fix this error. Any way the code below works for the most part (as long as your html is coded correctly). It would be easy to say well why don’t you just fix the html which would of course be easy assuming it is mine but in this situation it is not…. I do love actionscript3 it is definitely what adobe needed to do with actionscript it is nice because ActionScript three is not so different from C# and it is a full blown object oriented programming language. I have also attempted to get the information in JSON and render it but of course I run into the same issue. I will have you know you can do some cool stuff with the JSON class. I will be posting a new AIR application within the next 4-5 months.

?View Code ACTIONSCRIPTstage.scaleMode = StageScaleMode.NO_SCALE; var myXML:XML = new XML(); var XML_URL:String = "http://pipes.yahoo.com/pipes/pipe.run?_id=f207a19ea9a846e4ca242c5239a0d0df&_render=rss"; var myXMLURL:URLRequest = new URLRequest(XML_URL); var myLoader:URLLoader = new URLLoader(myXMLURL); //myLoader.addEventListener(Event.COMPLETE, onComplete); myLoader.addEventListener("complete", xmlLoaded); var outXML:XMLList = new XMLList(); var rssOutput:String; function xmlLoaded(event:Event):void { myXML = XML(myLoader.data); if (myXML.namespace("") != undefined) { default xml namespace = myXML.namespace(""); } myHead_txt.htmlText="Digg News"+"RIA News"+"MXNA News"+"MSDN News"; for each (var item:XML in myXML..item) { var itemTitle:String = item.title.toString(); var itemDescription:String = item.description.toString(); var itemLink:String = item.link.toString(); outXML += buildItemHTML(itemTitle, itemDescription, itemLink); } XML.prettyPrinting = false; rssOutput = outXML.toString(); myText_txt.htmlText=rssOutput; } function buildItemHTML(itemTitle:String, itemDescription:String, itemLink:String):XMLList { default xml namespace = new Namespace(); var body:XMLList = new XMLList(); body += new XML("<strong>" + itemTitle + "</strong>"); var p:XML = new XML(" "+ ""+" ");//remove the CDATA tag this was only an attempt to correct fubared html //var img:XML = <img alt="" /> var link:XML = <a></a>; link.@href = itemLink; link.font.@color = "#990000"; link.font = "More..."; p.appendChild( ); p.appendChild(link); body += p; return body; }

Managed to fix some of my issues. You will notice when you send a yahoo pipe through a feed validation some pipes absolutely explode. So of course their not going to work with flash. One work around is an attempt to cleanse the pipe so to speak I have had good results sending a dirty pipe through the Dapper to clean it. It is a round about process but it seems to work just fine. I have to give the people at yahoo credit yahoo pipes is truly amazing. I am also confident in the final release they will have no issues. While looking for ways to clean dirty html / xml I managed to teach myself a great deal! I also found this article that discusses how to use pipes to send a feed through a web page to append information creating the clean output of an rss feed combined with an html web page chunk sound weird I know. This displays an interesting use of the HTML tidy service. Any way check it out here. Bookmark and Share More »Powered by Bookmarkify™
