problem while fetching xml through some rss feed

[tariq2305]

I was fetching xml through some rss feed.
I am unable to sort items in depth like i have sorted easily "channel -> description" as

NSString *resultValue=[[responseDictionary valueForKeyPath:@"rss.channel.description"] textContent];

Above Result: YouTube RSS Feed


My question is how i can parse .... item -> description... i.e (Music video by Andrews \U00a9 1982 MJJ Productions Inc.)
i am getting nil if i fetch like valueForKeyPath:@"rss.channel.item.description"]

--------------------------------------------------------------------------------------
Key: rss Value: {
"_text" = "\n";
channel = {
"_text" = "\n";
description = {
"_text" = "YouTube RSS Feed";
};
item = (
{
"_text" = "\n\t";
description = {
"_text" = "Music video by Andrews \U00a9 1982 MJJ Productions Inc.";
};
enclosure = {
length = 294;
type = "application/x-shockwave-flash";
url = "http://youtube.com/v/Zi_XLOBDo_Y.swf";
};
link = {
"_text" = "http://youtube.com/?v=Zi_XLOBDo_Y";
};
