I did not understand what you wanted....
Fortunately, Chris did :-)

There is no (easy) build-in way to render strings as TAL templates.
You must create a template, wrap it and then render it.
This is possible only in an External Method or other external
Python code.

It will look somehow like:

   from Products.PageTemplates.ZopePageTemplate import ZopePageTemplate

   template= ZopePageTemplate('',your_template_string,'text/html')
   # now wrap it into a context
   wrappedTemplate= template.__of__(context)
   # render it
   renderResult= wrappedTemplate()
