Are you sure that is syntactically correct _VBScript_? Looks more like 
VB.NET to me. And if you use MSXML then for script you can use JScript 
or VBScript in XSLT but not the .NET languages.

Why are you trying to use MSXML in .NET anyway? .NET 1.x has 
XslTransform for XSLT transformations, .NET 2.0 has 
XslCompiledTransform. And then you could indeed use VB.NET as a 
"scripting" language in your XSLT stylesheets.
