I am looking for a way to filter out <IMG> tags from a Zope site. I'm =
using Zope 2.5.0 + CMF + CMFWiki. I have managed to modify the render =
routine of CMFWikiPage, but the request argument is empty, so I can't =
check to see if a cookie has been set.
What I want to do is examine a cookie called TextOnly. If the value is =
1, then the filter will replace all the Image tags with the ALT text. =
Otherwise, the filter will not be called.
As the code stands now, it's only modifying the contents of CMFWiki =
pages, leaving the outer framework of the site intact. What I want is to =
replace ALL image tags, so I need to get at something higher-level, like =
the entire HTML text just before it gets sent back to the browser.
