[xsl] Question of performance

["Ragulf Pickaxe" <jawxml@xxxxxxxxxxx>]

Hello everybody

I have a fairly large (41 KB) xsl document that is of course used for 
processing xml documents.

In this document I (usualy) declare the variables in the scope that I use 
them. Now it is found that I need a complex variable some 3-4 different 
places in this document.

My question is this: For best performance, is it best declare this variable 
as a global one, allocating memory for it for the whole duration or is it 
best to declare it where it must be used each and every time thereby having 
to process the declaration 4 times in a document?

Or is it even more times than 4 since the condition that leads to the use of 
the variable may be in an xml document many many times?

In case the answer to my question is processor dependent, I am using MSXML 
3.0.

(I hope that the question is clear enough stated).
Thank you for your time.
Ragulf Pickaxe :)
