我有一些默认命名空间的xml

<a xmlns='urn:test.Schema'><b/><b/></a>

并想要数数 <b/>

我该如何定义

XmlNamespaceManager nsmgr = ????
Assert.AreEqual(2, doc.SelectNodes("//b", nsmgr).Count);

断言变为真？

我到目前为止尝试过(使用nunit):

[Test]
[Ignore("Why does this not work?")]
public void __DoesNotWork_TestSelectWithDefaultNamespace()
{
    // xml to parse with defaultnamespace
    string xml = @"<a xmlns='urn:test.Schema'><b/><b/></a>";

    XmlDocument doc = new XmlDocument();
    doc.LoadXml(xml);

    // fails because xpath does not have the namespace
    //!!!!
    Assert.AreEqual(2, doc.SelectNodes("//b").Count);

    // using XPath defaultnamespace 
    XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
    nsmgr.AddNamespace("", "urn:test.Schema");

    // This will fail with dotnet 3.5sp1. Why?
    //!!!!
    Assert.AreEqual(2, doc.SelectNodes("//b", nsmgr).Count);
}
