I needed to select out XML nodes from an XML document that had namespaces attached and wasn’t getting the results I needed from my real code, so using snippet compiler I cooked up a simple example to get it working. Presented below is that simple example, here more as a reminder to myself if I need it again.

 using System;
using System.Xml;
public class XPathWithNamespaces
public static void Main()
XmlDocument xd = new XmlDocument();
test ");
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xd.NameTable);
nsmgr.AddNamespace("foo", "http://foo.bar/mouse");
XmlNode xn = xd.SelectSingleNode("//foo:theone", nsmgr);
if (xn != null)
