Welcome to the forum, yohan.

Could you pease attach a meaningful part of your input file as I guess the <form feed> char is NOT a text line on its own but part of a line without <new line> chars immediately around it.

And, please use code tags as required by forum rules.

---------- Post updated at 09:37 ---------- Previous update was at 09:35 ----------

And I guess, there should be one <FF> at least at the begin-of-file or end-of-file.

---------- Post updated at 09:45 ---------- Previous update was at 09:37 ----------

Based on above assumption, try:
Code:
awk '/\014/ {sub (/\014.*$/, ""); getline X; getline X} 1' file
Data 1
Data 2
Data 3
Data4
Data5
Data 6
Data 7

If that doesn't meet your expactations, the sample is indispensable.

business::isbn::data

Business::ISBN::Data(3) 				User Contributed Perl Documentation				   Business::ISBN::Data(3)

NAME

       Business::ISBN::Data - data pack for Business::ISBN

SYNOPSIS

       see Business::ISBN

DESCRIPTION

       You don't need to load this module yourself in most cases. "Business::ISBN" will load it when it loads.

       These data are generated from the RangeMessage.xml file provided by the ISBN Agency. You can retrieve this yourself at
       <http://www.isbn-international.org/agency?rmxml=1>.  This file is included as part of the distribution and should be installed at
       ~lib/Business/ISBN/RangeMessage.xml.

       If you want to use a different RangeMessage.xml file, you can set the "ISBN_RANGE_MESSAGE" environment variable to the alternate location
       before you load "Business::ISBN". This way, you can use the latest (or even earlier) data without having to install something new or wait
       for an update to this module.

       If the default RangeMessage.xml or your alternate one is not available, the module falls back to data included in Data.pm. However, that
       data is likely to be older data.

       The data are in %Business::ISBN::country_data (although the "country" part is historical). If you want to see where the data are from,
       check $Business::ISBN::country_data{_source}.

SOURCE AVAILABILITY

       This module lives in the Github repository with Business::ISBN:

	       git://github.com/briandfoy/business--isbn.git

       If you have something to add, create a fork on Github and send a pull request.
