Re: [xsl] C# code and .NET libraries in xslt stylesheet

One can use the standard .NET XSLT processor, implemented in the
XslCompiledTransform class. XslCompiledTransform is considered to be
the fastest XSLT 1.0 processor. It is supported by an extensive IDE
(editor and debugger)  that is part of Visual Studio.

A transformation can be initiated in C# (or any other .NET programming
language) code, or on the command line, using a utility such as Oleg
Tkachenko's nxslt.exe.

Extension objects (whose public methods are accessible to the
transformation)  and written in any .NET programming languges, can be
added before invoking the transformation.

This is the recommended way of adding and using extension objects.
There is a possibility to include inline in the transformation the
source code of extension functions, but this isn't recommended for
large-scale, server-side applications, as it gradually consumes all
available memory -- the dynamic dlls generated for the extension
functions in each invoked transformation cannot be unloaded without
stopping and starting IIS.

Here are some links:

1. The XslCompiledTransform class:

2. Adding extension methods to an XslCompiledTransform:

tensionobject.aspx

3. The nxslt.exe utility:

There are two known XSLT 2.0 processors that are closely related to
.NET -- Saxon.NET and more recently XQSharp. Please, see the related
documentation on the respective websites.
