Question

I want to transform my Xml with a Xslt file. Can I access to the Xml that is transforming with Xslt in an embedded code piece using C#.

<![CDATA[
    public string GetSomething(string path)
    {
        // Get the whole Xml that is transforming
        // And do something with it    
        // return result
    }
]]>

<xsl:value-of select ="GetSomething(courier:_appointment)"/>

Is it possible?

Thanks in advance,

There is some scripting support inside xslt, via <msxsl:script>, however: it is probably a better idea to use an extension object. Basically, you write a regular C# object (although you need to mark it as COM-callable, IIRC), and add it via XsltArgumentList, in particular AddExtensionObject – and in the process associate it with a particular urn. Your xslt then declares an xml namespace-alias for the url (i.e. xmlns:myExtension="blah blah"), and uses myExtension:someMethod(...) in the code.

There is a full example on MSDN.
