[Zope] Saving a Rendered DTML Document

Hello. I have a DTML document which contains some DTML, but mostly HTML. I want to save the HTML contents of this DTML document once it is rendered by Zope (i.e. once the DTML is evaluated) in another DTML document (i.e. this document will only contain HTML offcourse and must be since it will be used by a PHP script). Is there a way to do this so every time the former changes, the latter is updated as well? Any help would be appreciated. Thanks. - Asad
