Yes. At last. That's it. This works...

import DocumentTemplate
from Acquisition import Implicit

def dosearch(self):
	template = self.search.read_raw()

	completed = DocumentTemplate.HTML(template)
	theresult = completed(self, content='a')

	return(self, theresult)


Notes:
1) search is a DTML document that does a ZSQL query. This is the code that I want to modify (and ultimately, let others modify to their own specifications). This is *such* a big win for us...
2) In this snippet, content is defined in the Python code. In my real application it is obtained from a db lookup
3) the read_raw method is important, otherwise the template is HTML-quoted
4) Phillip is *the man*! :)

Many thanks Phillip, this has broken a huge log jam for me.

cheers again,
tone out.
