Transforming to an XmlWriter

[Scott]

The following blog gives a neat example of how to transform directly into a
node:

However, the code doesn't seem to work as it is presented in the blog. I
have put together the following three test cases to show this. The first two
work correctly, the last one doesn't. BTW...the last one is codes according
to the blog entry.

System.Xml.Xsl.XslCompiledTransform xslt = new
System.Xml.Xsl.XslCompiledTransform();
System.Xml.XmlDocument OutputDoc = null;
System.Xml.XmlWriter w = null;
xslt.Load(@"test.xslt");

OutputDoc = new System.Xml.XmlDocument();
using (w = OutputDoc.CreateNavigator().AppendChild()) {
xslt.Transform(@"test.xml", null, w);
}
OutputDoc.Save(@"out1.xml");

OutputDoc = new System.Xml.XmlDocument();
w = OutputDoc.CreateNavigator().AppendChild();
xslt.Transform(@"test.xml", null, w);
w.Flush();
w.Close();
OutputDoc.Save(@"out2.xml");

OutputDoc = new System.Xml.XmlDocument();
xslt.Transform(@"test.xml", null,
OutputDoc.CreateNavigator().AppendChild());
OutputDoc.Save(@"out3.xml");
