XPath-Navigable-Document from Nodelist

[Chucker]

I would like to select some nodes from a very large XML document and then
apply a stylesheet to the dom fragment / nodelist that is the result of my
XPath-Query.

It seems to me now that I have to build a new XMLDocument from the Nodelist
and apply the Stylesheet then. Is this realy neccessary or is there a simple
way to generate an "XPath-Navigable-Document" from my Nodelist wich I seem to
need for the XSLTransform?

This is the code where maybe just one statement is missing:

XMLOutput.Clear();
XmlTextReader tr = new XmlTextReader(textBox3.Text);
XmlValidatingReader vr = new XmlValidatingReader(tr);
vr.Schemas.Add("", textBox1.Text);
vr.ValidationType = ValidationType.Schema;
vr.ValidationEventHandler += new ValidationEventHandler(MyValidationHandler);
// load document with validating reader
XmlDocument doc = new XmlDocument();
// if we get past this, we know document is valid
doc.Load(vr);
XmlNodeList list = doc.SelectNodes(Filter.Text);
label4.Text = list.Count.ToString();
//So I got my Nodelist / DOM-Fragment here in "list" now XslTransform
myXslTransform;

***** XPathDocument myXPathDocument = new XPathDocument(list); ***** //This
does not work! How to do this? *******

myXslTransform = new XslTransform();
myXslTransform.Load(textBox2.Text);

System.IO.StringWriter stWrite = new System.IO.StringWriter();
myXslTransform.Transform(myXPathDocument, null, stWrite);

XMLOutput.AppendText(stWrite.ToString());

No, you don't have to create new document. Instead you can pass selected
nodeset (as XPathNodeIterator) as a parameter to XslTransform and
process it in XSLT.
