Using Xpath With Default Namespace in C#

Question

I\'ve got an XML document with a default namespace. I\'m using a XPathNavigator to select a set of nodes using Xpath as follows:

XmlElement myXML = ...;

First - you don't need a navigator; SelectNodes / SelectSingleNode should suffice.

You may, however, need a namespace-manager - for example:

XmlElement el = ...; //TODO
XmlNamespaceManager nsmgr = new XmlNamespaceManager(
    el.OwnerDocument.NameTable);
nsmgr.AddNamespace("x", el.OwnerDocument.DocumentElement.NamespaceURI);
var nodes = el.SelectNodes(@"/x:outerelement/x:innerelement", nsmgr);
