Re: [xsl] Variable Scope

[Karl Stubsjoen <kstubs@xxxxxxxxx>]

Update!
I am parsing with MSXML using the msxsl command interface and I do not
run into the scope error.  When I use my DOTNET transformation tool
(simple C# console app which uses the .net xml libraries) the error
appears.
If you can offer any input on this great.  Does anyone know if the
.net xml parser is the same as the standard msxml 4 library?
