Troubles with editing XSLT doc

[jernej goricki]

Hy I'm trying to edit a XSLT document, just like I'm editing a XML document
:
(Im trying to make a new xsl:template tag here )
Dim myXml As New XmlDocument()
myXml.Load(Server.MapPath("XSLLinks.xslt"))

Dim XmlLinks As XmlElement
Dim XmlNewLink As XmlElement
XmlLinks = myXml.SelectSingleNode("//xsl:stylesheet")
XmlNewLink = myXml.CreateElement("xsl:template")
XmlLinks.AppendChild(XmlNewLink)
myXml.Save(Server.MapPath("XSLLinks.xslt"))
But instead I get this error:

Namespace Manager or XsltContext needed. This query has a prefix, variable,
or user-defined function.

Do I have to edit a xslt document in a different way?
Thanks for your answer!

It won't work. You have to provide XmlNamespaceManager to resolve xsl
namespace prefix in //xsl:stylesheet expression.
See samples in SelectSingleNode method documentation at MSDN:

Hm...
I have some troubles with understanding this example

Dim doc As XmlDocument = New XmlDocument()
doc.Load(Server.MapPath("XSLLinks.xslt"))

'Create an XmlNamespaceManager for resolving namespaces.
Dim nsmgr As XmlNamespaceManager = New XmlNamespaceManager(doc.NameTable)
nsmgr.AddNamespace("xsl", "xsl:http://www.w3.org/1999/XSL/Transform")

........This probably isnt the right way to create a namespace for use in
xslt?

'Select the book node with the matching attribute value.
Dim book As XmlNode
Dim root As XmlElement = doc.DocumentElement
book = root.SelectSingleNode("stylesheet", nsmgr)

Read more about namespaces then, this is quite important topic when
working with XML.

No, it should be
nsmgr.AddNamespace("xsl", "http://www.w3.org/1999/XSL/Transform")

This associates xsl prefix with http://www.w3.org/1999/XSL/Transform
namespace name.
