[opencms-dev] newbie: parse & modify generated page

[Claus Priisholm]

Since you're on version 5 I suggest that you find the point where the 
editor saves the content of a page.

In version five the original content as typed by the user is saved along 
with a copy of the processed content (it gets jtidy'ed in order to 
isolate the links so OpenCms later can insert the right ones).

I managed to hook up some extra DOM processing in there. The advantage 
of this approach being that the overhead only occurs when saving rather 
than when viewing the page.

You can of course also use servlet filters, but that typically adds the 
overhead per page view.
