Is there a way to pass param array to xslt funtion in extended object of xsl? thanks.

You should pass it as XPathNodeIterator. There is no array type in XPath
data model.

Thanks for reply.

My problem is I am not sure how to combine several objects that include
string and XPath objects into one XPathNodeIterator.

The easiest way is to build XmlDocument or XPathDocument, then ask it to
create XPathNavigator, select nodelist of values and pass it.
StringWriter sw = new StringWriter();
XmlTextWriter w = new XmlTextWriter(sw);
w.WriteStartElement("root");
for (int i=0; i<10; i++)
w.WriteElementString("val", "value"+i);
w.WriteEndElement();
w.Close();
//XmlNodeWriter should be used instead of temporary string
XPathDocument doc = new XPathDocument(new StringReader(sw.ToString()));
XPathNavigator nav = doc.CreateNavigator();
XsltArgumentList args = new XsltArgumentList();
args.AddParam("array", "", nav.Select("/root/*"));

XPathDocument input = new XPathDocument("foo.xml");
XslTransform xslt = new XslTransform();
xslt.Load("foo.xsl");
xslt.Transform(input, args, Console.Out);

foo.xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:param name="array"/>
<xsl:template match="/">
<out>
<xsl:for-each select="$array">
<xsl:copy-of select="."/>
</xsl:for-each>
</out>
</xsl:template>
</xsl:stylesheet>

The result:
<out>
<val>value0</val>
<val>value1</val>
<val>value2</val>
<val>value3</val>
<val>value4</val>
<val>value5</val>
<val>value6</val>
<val>value7</val>
<val>value8</val>
<val>value9</val>
</out>

Thanks for your reply.

I think what I am trying to do is calling a extension object in dll from
xsl, I need the way to pass parameters to functions in the extension object
when they were called from xsl.

So, what's your problem actually? You can pass parameters to the
transformation and to exctension functions. But those parameters should
be only of fixed number of types. See

Hello,

I'm trying to send a XPathNodeIterator as xsl: param into a template:
the node set delivered by the iterator looks like this:

<childEntities parentEntity="AParentEntity">

<!-- child entities for AParentEntity -->
<entity name="aChildEntity" namespace="namespace.of.aChildEntity" table="aChildEntityTable" />

</childEntities>

the param name is ChildEntities and is added to an XsltArgumentList used by an XslCompiledTransform. I'm using .NET 2.0.

Inside the xslt template, the param is defined this way:
<xsl: param name="ChildEntities" />

However, this script does not produce anything:

<xsl: for-each select="$ChildEntities" >
// childentity
<xsl: copy-of select="."/>
</xsl:for-each>
:confused:

What is to be done?

Thank you,
Dan

Stupid me...
I was creating the XPathNodeIterator this way:
nav.Select( "/" ) instead of nav.Select( "/*" )
