Scripting with XslTransform
Creating and manipulating stylesheets is all well and good if all you need to do is use XSLT’s built-in abilities. But .NET’s XSLT tools can do a lot more. They allow you to execute arbitrary C#, Visual Basic, or JScript code embedded in the stylesheet, pass arguments to the XSLT processor, and call back to methods in your own C# code from expressions in the XSLT code.
Embedded scripts
.NET has the ability to interpret script
code embedded within the XSLT stylesheet. Example 7-9 shows the same catalog.xsl
stylesheet shown previously, but with a few minor changes.
I’ll explain the highlighted changes.
