adding text to the redered html

[source]

I have a few hundered pages, where there is one particular text which needs
to be formatted in a proper way. Currently the text comes from all different
souces(regex files, database and the text is hard coded too)
Now according to current legal terms and business rules I need to format
that particular text in a certain way.

I was wondering if I can change the text after ASP.net runtime has finished
redering the text and is about to send it to the browser, if I can intercept
the redered html page and search the redered page for the particular text
and made changes and then allow it go to the browser, I dont have to change
the regex/database files at all.

IS THIS POSSIBLE?

there is a prerender page event

maybe there's a post render one too?

Anybody can tell me if there is something equivaled to post render?
