Hi all,

I'm readming values from an rss feed, by way of the suplied xml file. Using
linq I can get the title and description, but need to know the last download
time. Can some one through me a hint. A snipit of the xml file
.

Thanks
Robert

XDocument doc = XDocument.Load(@"..\..\XMLFile1.xml");
XNamespace cfi =
"http://www.microsoft.com/schemas/rss/core/2005/internal";
foreach (XElement item in
doc.Root.Element("channel").Elements("item"))
{
Console.WriteLine("Item {0} downloaded at {1}.",
item.Element("title").Value, item.Element(cfi + "lastdownloadtime").Value);
}

This outputs the string value of the lastdownloadtime item, if needed
you could also convert it to a DateTime.
