Namespaces & Atom feeds

I'm new to XML namespaces, and I seem to be missing something obvious
in this code snippet, which is trying to retrieve the feed/entry nodes
from an XPathNavigator document:

XmlNamespaceManager mgr = new
XmlNamespaceManager(xpNav.NameTable);
mgr.AddNamespace("atom", "http://www.w3.org/2005/Atom");

XPathExpression itemsExpr = xpNav.Compile("/atom:feed/
atom:entry/");
itemsExpr.SetContext(mgr);

XPathNodeIterator items = xpNav.Select(itemsExpr);

The error comes back...

"The expression passed to this method should result in a NodeSet." --
and, indeed, the XPathNodeIterator doesn't result in any entries.

I'm using .Net 1.1. I believe this might affect the final code.

Thanks for any pointers.

Remove the final slash.
