I've tried to find the simplest demonstration of my issue. I have
source XML that looks like this (not a real XSD schema, but it doesn't
matter at this point):

(in var xmlStr:)
<xsd:element
xmlns:xsd="http://www.w3.org/2001/XMLSchema">abab</xsd:element>

Essentially, it's just an xml node w/ an xsd prefix, and the namespace
defined right on the node. Then, some jibberish is the text of the
node ("abab"). Using .NET, if I load this XML into an XmlDocument like
this:

XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlStr);
doc.SelectSingleNode("//xsd:element");

It tells me I need a namespace manager. So, I put one in my code like
this:

XmlNameTable nt = new NameTable();
XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);
nsmgr.AddNamespace("xsd", "http://www.w3.org//2001/XMLSchema");

Then, I call .SelectSingleNode("//xsd:element", nsmgr). Now, it's
null! What in the world?!? I feel like I'm missing something trivial
here. "//element" is also null, but I expected that because of my
namespace.

<xsd:element

xmlns:xsd="http://www.w3.org/2001/XMLSchema">abab</xsd:element>

nsmgr.AddNamespace("xsd", "http://www.w3.org//2001/XMLSchema");

You have 2 forward slash characters in the second case, note .org//2001

Thanks George. That was a typo. Anyone else?

Use Xpath in your SelectSingleNode call. Something like

doc.SelectSingleNode("Request/Element", nsmgr)
where xmlStr has the this node.

Post the contents of xmlStr to further help troubleshoot.
