Restrict based on form feed

[Garren]

Is there a way to restrict a filter to 15 lines after a form feed character (I thousands of pages in a document delimited by a form feed character). I just want to do a replace if it is the first 15 lines of each page.

Thank you,
Garren

Use a pattern as the restriction,

\f([^\r\n]*\r\n){15}
