Problem setting node-set in XsltArgumentLis t

[Sam]

I am working with .Net 2.0. I found a 2002 posting with this sample
code of how to send a node-set into a XSLT transformation:

string xml = @"<foo><bar> The Test</bar></foo>";
string xsl =
@"<xsl:styleshe et xmlns:xsl=""htt p://www.w3.org/1999/XSL/Transform""
version=""1.0"" >
<xsl:param name=""param1""/>
<xsl:template match=""/"">
bar element from param1 value:
<xsl:copy-of select=""$param 1/bar""/>
</xsl:template>
</xsl:stylesheet> ";

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml );
XPathNavigator nav = doc.CreateNavig ator();

XslTransform xslt = new XslTransform();
xslt.Load(new XmlTextReader(n ew StringReader(xs l)));

XPathDocument dummy = new XPathDocument(n ew
StringReader("< dummy/>"));
XsltArgumentLis t args = new XsltArgumentLis t();
//Pass element foo as parameter
args.AddParam(" param1", "", nav.Select("/foo"));
xslt.Transform( dummy, args, Console.Out);

The output I get is:

<?xml version="1.0" encoding="Windo ws-1252"?>
bar element from param1 value: <bar>The Test</bar>

If I am not mistaken, I should be getting:

<?xml version="1.0" encoding="Windo ws-1252"?>
bar element from param1 value: The Test

Does anyone know how to fix this sample to return the correct value?

Note that the preferred .NET 2.0 XSLT processor is XslCompiledTran sform
and not XslTransform.

string xml = @"<foo><bar> The Test</bar></foo>";

<xsl:copy-of select=""$param 1/bar""/>

<?xml version="1.0" encoding="Windo ws-1252"?>
bar element from param1 value: <bar>The Test</bar>

<?xml version="1.0" encoding="Windo ws-1252"?>

Why, xsl:copy-of copies the selected node, in this case the bar element,
to the result tree. So you end up with a copy of the complete element in
the result tree, that is the expected behaviour.
