[Zope] setting Title vars automatically on ftp uploaded html docs

I am migrating a clients static html site to zope to utilize the management features of zope. I'm indexing and searching the site with a ZCatalog and have manually set the Title vars on each dtml document so I can display it on the search results page. My question is how to go through their folder and search dtml documents for the <title></title> tags not containing <dtml-var> tags and update the Title var for that document. I was thinking of using an external method run periodically but I'm not sure if I can access a folder and all it's objects and set those variables externally. -- Chris McClimans chris-zope@mcclimans.net
