AS3 RSS FEED XML Namespace

Question

AS3 - FLASH 10
Hello,
I'm having some trouble understanding how can I access a tag in a xml RSS Feed 2 format. Some tags have, what I think to be, namespaces that just ignore my request when accessing such tag. Here is an example:
// XML LOADED
<rss>
<channel>
<item>
    <title>POST TITLE</title>
    <link>http://domain.org/blog/2009/08/post-name/</link>
    <comments>http://domain.org/blog/2009/08/post-name/#comments</comments>

    <description><![CDATA[DATA[...]]]></description>
    <content:encoded><![CDATA[DATA]]></content:encoded>
    <wfw:commentRss>http://domain.org/blog/2009/08/post-name/feed/</wfw:commentRss>
    <slash:comments>0</slash:comments>
</item>
</channel>
</rss>
// FLASH CODE
trace ( xml.channel.item.title ) // Output POST TITLE
trace ( xml.channel.item.content ) // Output undefined or “”
… same for wfw and slash tags.
Any help?
Regards

One of the ways is to use regular expressions and replace all the unwanted namespaces with pure tags:
1. Get the xml data as string:
var xmlString:String = [write the data here]
2. Pattern for the tags with namespaces is something like this:
var exp:RegExp = /<\\|(\w+):(\w+)>/gi;
3. This is just to demostrate what it outputs: - is not needed in the final code
var tagsArray:Array = xmlString.match(exp);
var currentOccurance:Array;
for (var i:int = 0; i < tagsArray.length; i++) {
     currentOccurance = tagsArray[i].split(":");
     trace("left = " + currentOccurance[0] + "; right = " + currentOccurance[1]);
It outputs something like this:
left = content; right = encoded>
left = content; right = encoded>
left = wfw; right = commentRss>
left = wfw; right = commentRss>
left = slash; right = comments>
left = slash; right = comments>
4. Depending on what side you want to use in the final tag:
a. If left:
xmlString = xmlString.replace(exp, "$1");
It will make the following changes:
From:
<content:encoded>....</content:encoded>
<wfw:commentRss>...</wfw:commentRss>
To:
<content>....</content>
<wfw>...</wfw>
b. if right:
xmlString = xmlString.replace(exp, "$2>");
It will make the following changes:
To
<encoded>....</encoded>
<commentRss>...</commentRss>
The final code is actually 4 lines only (assuming you use complete event):
var xmlString:String = e.target.data;
var exp:RegExp = /<\\|(\w+):(\w+)>/gi;
xmlString = xmlString.replace(exp, "$1");
var myXML:XML = new XML(xmlString);
Viola! You can parse xml regular way.
