How to Capture Output from print_output()
 

I'd very much like to do some post-processing of the output of print_output(), however, it is flushing its output to the connection.

I've attempted to turn on output buffering before my call to print_output, an then catch the output via ob_get_contents(), but the explicit flush() call inside of print_output() is making that method fail.

So, is there any other way to capture the output from print_output() into a variable before sending it to the browser?

Thanks!

Thanks Lynne,
Unfortunately I need to do processing on the final HTML, and print_output replaces variables that fetch_template does not.
