Editing the contents of the PrintWriter

Hello:

I am in a situation as follows:

My servlet is calling a stored procedure that writes HTML. I want to extract values from that HTML and do further processing with them and I want to edit the HTML. So after I make the call, I want to parse the contents of response.getWriter(). I am assuming that the stored procedure output is accessible there.

I cannot figure out a way to do this. Any ideas?

Sounds like you need a response wrapper and filter.

Or back up a bit and stop defining HTML at the DB layer. Never the best of ideas. Have the stored procedure produce an abstract data model that you can use to generate HTML at the appropriate time.
