now i would like to have the url from the second link tag wich is the poster image. How can i select this within as3? I tried the following:

for each(var entryXML:XML in resultXML.rootNamespace::entry)
            {
                    trace(entryXML.rootNamespace::link.@href);


            }

But this also gives me the href from the first link. So how can i filter this so i only get the href from the second link?

Try something like this:

var imageUrl : String = entryXml.link.(@type=="image/png").@href;
