Why can't I access xml nodes with out namespaces?


I've been banging my head on my desk for hours trying to figure out why I can't access the entry.author.name content? I've tried every possible way to access it but failed.

But when I loop through all nodes with xml.children I see the author node.

I see the author node is apart of the atom namespace but it doesn't have a namespace like the other namespaces.

package {
    import flash.display.Sprite;

public class Gdata extends Sprite { private var xml:XML = <entry xmlns="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/" xmlns:gd="http://schemas.google.com/g/2005" xmlns:yt="http://gdata.youtube.com/schemas/2007"> http://www.w3.org/2005/Atom,http://search.yahoo.com/mrss/,http://schemas.google.com/g/2005, http://gdata.youtube.com/schemas/2007 <id> http://gdata.youtube.com/feeds/api/videos/bwbZJw-C4Jk </id> <published> 2009-04-17T19:11:48.000Z </published> <updated> 2009-04-29T10:19:50.000Z </updated> <category scheme="http://gdata.youtube.com/schemas/2007/categories.cat" term="News" label="News & Politics"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="Garofalo"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="Olbermann"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="commentary"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="Janeane"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="news"/> <category scheme="http://schemas.google.com/g/2005#kind" term="http://gdata.youtube.com/schemas/2007#video"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="Keith"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="analysis"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="Party"/> <category scheme="http://gdata.youtube.com/schemas/2007/keywords.cat" term="Tea"/> <title type="text"> Janeane Garofalo Calls Tea Party Protesters Racists </title> <content type="text"> Janeane Garofalo: http://tinyurl.com/cr6rt8 EPA: http://tinyurl.com/clpyqo Veterans: http://tinyurl.com/ckbhb6 DHS: http://tinyurl.com/cctf54 DHS2: http://tinyurl.com/dahaxr John Ziegler: http://tinyurl.com/d7qbo4 Teabagging: http://tinyurl.com/ddskjo </content> <link rel="alternate" type="text/html" href="http://www.youtube.com/watch?v=bwbZJw-C4Jk"/> <link rel="http://gdata.youtube.com/schemas/2007#video.responses" type="application/atom+xml" href="http://gdata.youtube.com/feeds/api/videos/bwbZJw-C4Jk/responses"/> <link rel="http://gdata.youtube.com/schemas/2007#video.related" type="application/atom+xml" href="http://gdata.youtube.com/feeds/api/videos/bwbZJw-C4Jk/related"/> <link rel="http://gdata.youtube.com/schemas/2007#mobile" type="text/html" href="http://m.youtube.com/details?v=bwbZJw-C4Jk"/> <link rel="self" type="application/atom+xml" href="http://gdata.youtube.com/feeds/api/videos/bwbZJw-C4Jk"/> <author> <name> HowTheWorldWorks </name> <uri> http://gdata.youtube.com/feeds/api/users/howtheworldworks </uri> </author> <gd:comments> <gd:feedLink href="http://gdata.youtube.com/feeds/api/videos/bwbZJw-C4Jk/comments" countHint="2249"/> </gd:comments> <media:group> <media:category label="News & Politics" scheme="http://gdata.youtube.com/schemas/2007/categories.cat"> News </media:category> <media:content url="http://www.youtube.com/v/bwbZJw-C4Jk&f=videos&app=youtube_gdata" type="application/x-shockwave-flash" medium="video" isDefault="true" expression="full" duration="236" yt:format="5"/> <media:content url="rtsp://rtsp2.youtube.com/CiILENy73wIaGQmZ4IIPJ9kGbxMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp" type="video/3gpp" medium="video" expression="full" duration="236" yt:format="1"/> <media:content url="rtsp://rtsp2.youtube.com/CiILENy73wIaGQmZ4IIPJ9kGbxMYESARFEgGUgZ2aWRlb3MM/0/0/0/video.3gp" type="video/3gpp" medium="video" expression="full" duration="236" yt:format="6"/> <media:description type="plain"> Janeane Garofalo: http://tinyurl.com/cr6rt8 </media:description> <media:keywords> Janeane, Garofalo, Keith, Olbermann, Tea, Party, commentary, analysis, news </media:keywords> <media:player url="http://www.youtube.com/watch?v=bwbZJw-C4Jk"/> <media:thumbnail url="http://i.ytimg.com/vi/bwbZJw-C4Jk/default.jpg" height="90" width="120" time="00:01:58"/> <media:thumbnail url="http://i.ytimg.com/vi/bwbZJw-C4Jk/1.jpg" height="90" width="120" time="00:00:59"/> <media:thumbnail url="http://i.ytimg.com/vi/bwbZJw-C4Jk/3.jpg" height="90" width="120" time="00:02:57"/> <media:thumbnail url="http://i.ytimg.com/vi/bwbZJw-C4Jk/0.jpg" height="240" width="320" time="00:01:58"/> <media:title type="plain"> Janeane Garofalo Calls Tea Party Protesters Racists </media:title> <yt:duration seconds="236"/> </media:group> <gd:rating average="3.9231105" max="5" min="1" numRaters="2289" rel="http://schemas.google.com/g/2005#overall"/> <yt:statistics favoriteCount="304" viewCount="33463"/> </entry>;

Solution

  • Try this ...

    public function Gdata()
    {
        var atom:Namespace = new Namespace("http://www.w3.org/2005/Atom");
        var media:Namespace = new Namespace("http://search.yahoo.com/mrss/");
        var gd:Namespace = new Namespace("http://schemas.google.com/g/2005");
        var yt:Namespace = new Namespace("http://gdata.youtube.com/schemas/2007");
    
        default xml namespace = atom; // IMPORTANT
    
        trace("0",xml.children()[22]);                  
        trace("1",xml.inScopeNamespaces());
        trace("2",xml..media::group);                   
        trace("3",xml..yt::statistics.@favoriteCount);                  
        trace("4",xml..yt::duration.@seconds);                  
        trace("5",xml..author ); // why?????????
        trace("6",xml.author ); // why?????????
    
        var x:int = 0;
        for each (var i in xml.children())
        {
            if(i.localName() == 'author')
            {
                trace("author", i);
            }
        }
    }
