Splitting a file based on context.
I have file as shown below. Would like to split the file based on the context of data.
Like, split the content between "---- XXX Info ----" and "
---- YYY Info ----" to a file.

When I try using below command, 2nd file contains all the info starting after first "---- YYYY Info ----" instance.
Code:
csplit -ks pfm.txt '%XXX Info%' '/^---- YYY Info ----/' {2}

Any suggestions how to split the only reqd. data as mentioned above.
Code:
---- XXX Info ----
Buuuu xxx bbb
Kmmmm rrr ssss uuuu
Kwwww zzzz ccc
Roooowwww eeee
Bxxxx jjjj dddd
---- YYY Info ----
Kuuuu eeeee nnnn

app::info::handler::prompt

App::Info::Handler::Prompt(3pm) 			User Contributed Perl Documentation			   App::Info::Handler::Prompt(3pm)

NAME

       App::Info::Handler::Prompt - Prompting App::Info event handler

SYNOPSIS

	 use App::Info::Category::FooApp;
	 use App::Info::Handler::Print;

	 my $prompter = App::Info::Handler::Print->new;
	 my $app = App::Info::Category::FooApp->new( on_unknown => $prompter );

	 # Or...
	 my $app = App::Info::Category::FooApp->new( on_confirm => 'prompt' );

DESCRIPTION

       App::Info::Handler::Prompt objects handle App::Info events by printing their messages to "STDOUT" and then accepting a new value from
       "STDIN". The new value is validated by any callback supplied by the App::Info concrete subclass that triggered the event. If the value is
       valid, App::Info::Handler::Prompt assigns the new value to the event request. If it isn't it prints the error message associated with the
       event request, and then prompts for the data again.

       Although designed with unknown and confirm events in mind, App::Info::Handler::Prompt handles info and error events as well. It will simply
       print info event messages to "STDOUT" and print error event messages to "STDERR". For more interesting info and error event handling, see
       App::Info::Handler::Print and App::Info::Handler::Carp.

       Upon loading, App::Info::Handler::Print registers itself with App::Info::Handler, setting up a single string, "prompt", that can be passed
       to an App::Info concrete subclass constructor. This string is a shortcut that tells App::Info how to create an App::Info::Handler::Print
       object for handling events.

INTERFACE

   Constructor
       new

	 my $prompter = App::Info::Handler::Prompt->new;

       Constructs a new App::Info::Handler::Prompt object and returns it. No special arguments are required.
