Does anybody know if it is possible in a compound template to use a string item in the package and execute it as if were a dreamweaver template? And whether you apply the same method to other mediators (like razor)?
Thanks Mark

I'm afraid that won't be possible on just any item in the Package
, since the Engine
expects Template
s to be based on Tridion items.
If your Template Item is based on a Tridion Item you can probably get pretty far by starting at the Engine.GetMediator
method. If it isn't, you'll have to find some way to turn it into a valid Template
object.
Template template = ...
IMediator mediator = engine.GetMediator(template);
mediator.Transform(engine, template, package);
When I have to create a Component
object from a Tridion-based Item in the Package, I normally do something like this:
Component component = new Component(item.GetAsXmlDocument().DocumentElement,
engine.GetSession);
I haven't tried, but expect that you can do the same for a Template
- given that you start with a valid Item from the Package representing a Template to begin with. You can probably clone the XML from an existing Item or find some other way to fake it.
If you get this to work, it will work across all registered template types. The Engine
provides no special treatment for the types that come with Tridion.
engine.GetMediator
is not public, so you can't reach it. I ended up simply instantiating the DreamweaverMediator
in my TBB and passing in my pre-constructed TemplateBuildingBlock
object. I'll update the code above if more people find it useful. –
Rida I suspect this is not possible.
Package.EvaluateExpression
may be useful, but as the name suggests it'll only work on expressions, not large snippets of code with embedded expressions (i.e. TEL)
Engine.GetMediator
expects a Template
and returns the appropriate Mediator
for it. Your problem then is that the IMediator
interface only defines the Transform
method, which requires an Engine
, a Template
and a Package
.
I can't think of any elegant ways around these. Maybe write your own Mediator, but that would still expect a Package, not a string, so you'd have to first store the string based Item from another TBB.
My advice: Sounds like you need to go back to the drawing board and find an alternative solution to your problem.

package.EvaluateExpression(string expression)
that might be worth investigating. – Eczema
