i am using xpath to navigate through this xml file.
i used the following code to navigate through items node.

XmlDocument doc = new XmlDocument();
doc.Load(xmlfile);

XPathNavigator nav = doc.CreateNavigator();
XPathExpression exp = nav.Compile("rss/channel/item");

XPathNodeIterator iterator = nav.Select(exp);
XPathNodeIterator iter1;
while (iterator.MoveNext())
{
iter1 = iterator.Current.SelectChildren("media:content", "");
if (iter1.Count > 0)
{
while (iter1.MoveNext())
{
if (iter1.Current.HasAttributes == true)
{
string url = iter1.Current.GetAttribute("url", "");
}
}
}
}

but when i execute the code, the iter1.count always returns zero. if i select anyother children(like title or description)i am able to display the value.but when i select media:content(one of the subitems of item) i am not able to display the attribute value.

Where am i going wrong?

Any suggestions please

regards
