I have the following XML document.

<?xml version="1.0" encoding="utf-16"?>
<xd:xmldiff version="1.0" srcDocHash="6067335156532207495" options="None"
fragments="no"
xmlns:xd="http://schemas.microsoft.com/xmltools/2002/xmldiff">
<xd:node match="1">
<xd:node match="1">
<xd:node match="4">
<xd:node match="3">
<xd:change match="@version">2</xd:change>
</xd:node>
</xd:node>
</xd:node>
</xd:node>
</xd:xmldiff>

If I take the prefixes off, the following query works as I would expect:
XmlNodeList rootNodes = changeDoc.SelectNodes("/xmldiff/node", nsmanager);

What does the code look like with the namespace prefix?

TIA.

Did you add the XmlDiff namespace URI to nsmanager? and
if so, what prefix did you give it? That prefix must appear in
the XPath expression, too.

XmlNamespaceManager nsManager =
new XmlNamespaceManager( changeDoc.NameTable);
nsManager.AddNamespace( "diff",
"http://schemas.microsoft.com/xmltools/2002/xmldiff");
XmlNodeList rootNodes = changeDoc.SelectNodes(
"/diff:xmldiff/diff:node", nsManager);

I use 'diff' to demonstrate that the choice of namespace prefix
added to the XmlNamespaceManager is irrelevant, it's the
namespace URI that counts.
