     <description>Ok, de regalo de San Valentin me pueden dar un viaje a &lt;b&gt;Playa&lt;/b&gt; del Carmen! Digo, entre todos lo pagan! No?? &lt;a href=&quot;http://search.twitter.com/search?q=%23So%C3%B1arNoCuestaNada&quot; onclick=&quot;pageTracker._setCustomVar(2, 'result_type', 'recent', 3);pageTracker._trackPageview('/intra/hashtag/#So&#241;arNoCuestaNada');&quot;&gt;#So&#241;arNoCuestaNada&lt;/a&gt;</description>

     <twitter:metadata> 
     <twitter:result_type>recent</twitter:result_type> 
     </twitter:metadata> 
    </item>

和我讀到<title>和<pubDate>使用：

function rssLoaded(evt:Event):void { 
    rssXML = XML(rssLoader.data); 
    for(var item:String in rssXML.channel.item) { 
    fechas.push(rssXML.channel.item[item].pubDate.substr(0, 16)); 
    titulos.push(rssXML.channel.item[item].title); 
    trace(rssXML.channel.item[item].media:content.attributes.url); 
    total=total+1; 
    } 
    trace(total); 
}

但是，trace(rssXML.channel.item[item].media:content.attributes.url);永遠是空的，所以我怎麼能讀取標籤<media>屬性網址 ???謝謝！

@屬性標識符

用法

[email protected]

Identifies attributes of an XML or XMLList object. For example, [email protected] identifies attributes named id for the myXML XML object. You can also use the following syntax to access attributes: myXML.attribute("id"), myXML["@id"], and [email protected]["id"]. The syntax [email protected] is recommended. To return an XMLList object of all attribute names, use @*. To return an attribute with a name that matches an ActionScript reserved word, use the attribute() method instead of the @ operator.

var myXML:XML = 
    <item id = "42"> 
     <catalogName>Presta tube</catalogName> 
     <price>3.99</price> 
    </item>; 

trace([email protected]); // 42

你的情況：

trace(rssXML.channel.item[item].media:[email protected]);
