Here is the same reply I put on the microsoft.public.xsl list:
They are processed very differently by the .NET framework, and you should
refrain from using msxsl:script elements within XSLT parsed by managed code.
See Q316775 [1], the assembly cannot be unloaded correctly and may lead to a
memory leak. There are several design patterns that you can use to mitigate
the changes, including dynamically loading an assembly that contains your
extension objects.
Not that it is impossible to do, but I have not seen any vendors that
support script debugging in their XSLT products. For example, Marrowsoft's
Xselerator is one of the best XSLT IDEs and it does not support script
debugging. I have not seen ActiveState's newest release of their XSLT
debugger for .NET, but I have not heard about it being able to debug inlined
script, either.
Your best bet is to simply use extension objects if you are using .NET.

Also, does the VS debugger work for you with the contents of the
msxsl:script tag ?
I had't tried it until just now. The only way I could think of doing
this was using 'step into' xsltTrans.transform(....)', but that doesn't
work. The callbacks to myObject.someMethod can be debugged if I place a
breakpoint there, but I can't place break points inside the
msxsl function because it's only a string inside a data file afa
devStudio is concerned.

news:<bo**********@rex.ip-plus.net>...I think the subject says it all, but just in case:
I know that I can call my own methods during an XSL transformation
using
<xsl:value-of select="myObject.someMethod(arg1)" />
having done something like:
dim xslTrans as System.Xml.Xsl.Xsltransform
dim xsltArg as new System.Xml.XsltArgumentList()
xsltArg.AddExtensionObject("urn:my-object")
....
dim navigator as System.Xml.Xpath.XPathNavigator = ..
xslTrans.transform(navigator, xslArg, myWriter, Nothing)
...
public function someMethod( arg as string) as String
...
end function
and I also know that I can define functions in a script inside
the xsl file using:
<msxsl:script language="VisualBasic" implements-prefix="user">
function myFunc (xx)
...
end function
</msxsl:script>
<xsl-value-of select="user:myFunc( elm/@value ) />
Is there an easy way to combine the two ideas so that my msxml:script
function calls the method of my extension object ?
<msxsl:script language="VisualBasic" implements-prefix="user">
<![CDATA[
function myFunc (xx)
myFunc = myObject.someMethod()
end function
]]>
</msxsl:script>
Steve.
