I'm having performance/memory problems using .NET's XslTransform class so I
thought I'd give the MSXML object's a whirl.
The question I haven't been able to find in these groups is can I use C#
extension functions with the MSXML objects? More specifically to use a C#
class which has all my extension functions.
I've seen examples where the stylesheet uses the <msxsl:script > element and
embeds C# code, but that's not a viable solution for my situation since I'll
be maintaining lots of different stylesheets which require the same
extension functions. (if I make one edit to an extension function, I don't
want to open up 20 other files and make the same edits)
Thanks,

Have you optimized your code, as recommended in "Improving XML
Performance" paper? [1]

You cannot. MSXML only supports scripting languages like JScript or
VBScript for extension functions.
Well, basically COM can call .NET code via interop (read about COM
Callable Wrappers in .NET), so you can register a .NET assembly on the
machine and then call its methods from COM.
But I doubt that's going to improve your perf problem, not to mention
lots of additional problems with interop. You can try it though.

That won't work with MSXML anyway.

Nope, looks like the article came out last month so I haven't come across it
yet. Looks like a good comprehensive article which I'll be sure to read.

Slightly confused here. You say no here, but it looks like below you say it
is possible through COM. Is that right?

I'm familiar with creating CCW in .NET, just not with the syntax of MSXML.
I don't suppose you could provide a quick example of how you would use a COM
object for extension functions in MSXML? The other thing is, a lot of
people compare the speed improvements of MSXML over the .NET implementation,
however, not much is mentioned about memory. For my particular situation,
I'm more concerned with memory. How do the two implementations compare? Is
it neglible enough to not bother wasting my time testing MSXML?
Thanks,

MSXML allows JScript/VBScript extensions, where you can instantiate
ActiveX objects and I presume work with COM somehow.

That's just VBScript or JScript.

I'm not sure what's the best here. You better try and measure.

if some two or more threads try to change these data types,

returning and catching this dummy value, the POSTs perform

Is there a table which has the name of the extension and the functions
