Problem traversing XML object

[lmitchsmith]

Hi

I am experiencing problems when trying to traverse XMl returned from the youtube data api

I can trace the XML but cannot access any of the nodes, not sure where I'm going wrong, I have tried various methods including parsing JSON format from youtube but to no avail.

I thought it maybe the namespaces so I replaced these using a script to replace them as attributes. A snippet of returned XML is below:

CODE:

XML.ignoreWhitespace = true;
var xmlString:XML = new XML(event.target.data);

var modified:String = xmlString.replace("xmlns=", "xmlns:default=");

var pattern:RegExp = new RegExp("?!/)", "gi");
var transmuted:String = modified.replace(pattern, "_");

var ab:String = transmuted.toString();
var zones:XML;
zones=new XML(ab);
trace(zones); //traces XML document

//trace(zones[0].entry[0].id) // produces a term has no properties
//trace(zones[0].feed[0].entry[0].id) //produces undefined

Any help with this is greatly appreciated

Thanks

You code looks AS2 and yes it is. So use this code in a fla timeline and save the fla and the feed.xml file in same directory. And test it.

var xml:XML = new XML();
xml.ignoreWhite = true;
xml.onLoad = function(success) {
    var node = xml.firstChild;
    trace(node.attributes.xmlns_app);
    trace(node.attributes.xmlns_media);
    trace(node.childNodes[0].firstChild);
};
xml.load("feed.xml");

Thanks yep that works in AS2 project

traces:

http://purl.org/atom/app#
http://search.yahoo.com/mrss/
http://gdata.youtube.com/feeds/api/videos

How would I traverse it in AS3?
