Help with Extension Objects in XSLT with C# .NET 1.1

Expand|Select|Wrap|Line Numbers

 <?xml version="1.0" encoding="UTF-8" ?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"  

                xmlns:TP="urn:TemplateParser">

<xsl:template match="/">

  <html>

  <body>

        <h3>DATA Tag Replacement Example</h3>

        <p>

        Name = <b><xsl:value-of select="TP:GetValue('NAME')"/></b>

        </p>
 
        <h3>CONDITION Tag Replacement Example</h3>

        <p>I drive

        <xsl:if test="TP:IsConditionTrue('HONDA')"> an Accord.</xsl:if>

        <xsl:if test="TP:IsConditionTrue('TOYOTA')"> a Camry.</xsl:if>

        </p>
 
        <h3>REPEAT Tag Replacement Example</h3>

        <p>Friends characters...

        <table>

            <tr><th>NAME</th><th>GENDER</th></tr>

            <xsl:for-each select="TP:IsRecordAvailable('Friends')-->

                <tr>

                    <td><xsl:value-of select="TP:GetRepeatValue('Friends', 'Name')"/></td>

                    <td><xsl:value-of select="TP:GetRepeatValue('Friends', 'Gender')"/></td>

                </tr>

            </xsl:for-each>

        </table>

        </p>

  </body>

  </html>

</xsl:template>

</xsl:stylesheet>

I have a class named TP that has the methods GetValue(s), GetRepeatValue(s), IsConditionTrue(s) etc implemented.

I am doing a Transform with a dummy XML file (no data), the above XSL file and the TP class like this:

Expand|Select|Wrap|Line Numbers

 XPathDocument xmlDoc = new XPathDocument( xmlDocName );

XslTransform xslt = new XslTransform();

xslt.Load( xslDocName );

XsltArgumentList xsltArgList = new XsltArgumentList();

TP tpObj = new TP();

xsltArgList.AddExtensionObject( "urn:TemplateParser", tpObj );

XmlTextWriter writer = new XmlTextWriter( output, null );

xslt.Transform( xmlDoc, xsltArgList, writer, null );

THIS WORKS for the value and if-condition, BUT NOT for the for-each. I am not sure what I need to return from my TP class for the for-each. I tried 1 (true) and 0 (false) but it didn't work.

TIA

EDIT:

Instead of a dummy XML file, I replaced the line like this:

Expand|Select|Wrap|Line Numbers

 XPathDocument xmlDoc = new XPathDocument( new StringReader( "<doc/>" ) );
 

FYI the TP class will hold on to any collections and their iterators, and when each "repeat value" is requested for, the corresponding value will be returned. At least that was my idea for the implementation.
