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(t extBox3.Text);
XmlValidatingRe ader vr = new XmlValidatingRe ader(tr);
vr.Schemas.Add( "", textBox1.Text);
vr.ValidationTy pe = ValidationType. Schema;
vr.ValidationEv entHandler += new ValidationEvent Handler(MyValid ationHandler);
// 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.ToSt ring();
//So I got my Nodelist / DOM-Fragment here in "list" now XslTransform
myXslTransform;

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

myXslTransform = new XslTransform();
myXslTransform. Load(textBox2.T ext);

System.IO.Strin gWriter stWrite = new System.IO.Strin gWriter();
myXslTransform. Transform(myXPa thDocument, null, stWrite);

XMLOutput.Appen dText(stWrite.T oString());

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