XSLT transforms and complex parameter types

[cameron]

I am attempting to pass in an XmlDocument as a parameter to a transform:

from my sample ASPX page:

string BaseDir = "/cameron/Play/ComplexParam/";

XmlDocument XSL = new XmlDocument();
XSL.Load(HttpContext.Current.Server.MapPath(BaseDir + "xsl.xsl"));

XmlDocument Data = new XmlDocument();
Data.Load( HttpContext.Current.Server.MapPath(BaseDir + "Data.xml") );

XmlDocument Betty = new XmlDocument();
Betty.LoadXml("<betty>Betty text<whooo>" +
"Woo text</whooo><weee/></betty>");

StringWriter Results = new StringWriter();

XslTransform XSLT = new XslTransform();
XSLT.Load(XSL.DocumentElement.CreateNavigator(),
new XmlUrlResolver(),
Assembly.GetCallingAssembly().Evidence);

XsltArgumentList Args = new XsltArgumentList();
Args.AddParam("InXML", "", Betty.DocumentElement);
//Args.AddParam("InXML", "", Betty);
//Args.AddParam("InXML", "", (XmlNode)Betty.DocumentElement);

XSLT.Transform(Data.DocumentElement.CreateNavigator(),
Args, Results, (XmlResolver)null);

HttpContext.Current.Response.Write("Transform = " +
Results.ToString());

---------------------------------------------

Data.xml:
<?xml version="1.0" encoding="utf-8" ?>
<Data>
<SomeData>Data-here</SomeData>
</Data>

---------------------------------------------

xsl.xsl
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:user="http://mycompany.com/mynamespace"
exclude-result-prefixes="msxsl user"
version="1.0">

<xslutput method="xml" omit-xml-declaration="yes"/>

<xslaram name="InXML"/>

<xsl:template match="/">
got root
<xsl:if test="$InXML">
<p>InXml looks good to me!</p>

<p>whoo count <xsl:value-of select="count($InXML/whooo)"/></p>
<p>weee count <xsl:value-of select="count($InXML/weee)"/></p>
<p>text '<xsl:value-of select="$InXML/text()"/>'</p>
<xsl:for-each select="$InXML/whooo">
<p>have child</p>
</xsl:for-each>
</xsl:if>
</xsl:template>

</xsl:stylesheet>

---------------------------------------------

Output:
got root
InXml looks good to me!
whoo count 0
weee count 0
text ''

---------------------------------------------

I can do this in IE as a client-side transform without issue but not in
C#. Can anyone see what I am doing wrong?

Thanks

Hi Cameron,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that XSLTransform works incorrectly when the
parameter contains node. If there is any misunderstanding, please feel free
to let me know.

Based on my research, this is a known issue in current .net framework.
Since IE uses MSXML to process xml data, it is working properly. This issue
will be fixed in the next version of .net framework. Currently, I think you
have to use MSXML to process with the xsl.

HTH.
