I have been trying to parse the below XML file (kuler
rss feed). I have read the various posts on this site but am unable to piece them together.
I specifically want to extract the child(or siblings) nodes of the element <kuler:themeItem>.
However I am getting an exception :
Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function.
Pl help : C# 3.0 net framework 3.5
RSS feed snippet:

My Code so far:
static void Main(string[] args)
{
const string feedUrl =
"http://kuler-api.adobe.com/rss/get.cfm?listtype=recent&key=xxxx";
var doc = new XmlDocument();
var request = WebRequest.Create(feedUrl) as HttpWebRequest;
using (var response = request.GetResponse() as HttpWebResponse)
{
var reader = new StreamReader(response.GetResponseStream());
doc.Load(reader);
}
XmlNodeList rsslist = doc.SelectNodes("//rss/channel/item/kuler:themeItem");
for (int i = 0; i < rsslist.Count; i++)
{
XmlNode rssdetail = rsslist.Item(i).SelectSingleNode("kuler:themeTitle");
string title = rssdetail.InnerText;
Console.WriteLine(title);
}
}
}
