Splitting XML file on basis of line number into multiple file

Hi All,

I have more than half million lines of XML file , wanted to split in four files in a such a way that top 7 lines should be present in each file on top and bottom line of should be present in each file at bottom.

from the 8th line actual record starts and each record contains 15 lines means from 8th to 22nd line is the first record of the file.
so the total number of actual records are varying each time.

wanted to divide this actual record in four chunks and each chunks should move to new four files respectively below to the top 7 and above the bottom line.

say...
Code:
cat ABCD.xml |wc -l
 690728
Actual Record lines = 690728 -[top 7] -[bottom1]= 690720
690720/15 = Actual Record = 46048

then
46048/4 = 11512 or [if it is not exactly divisible then the remainder record should move to the last ]


so first 11512 record move to ABCD_part1.xml
second 11512 will move to ABCD_part2.xml
third 11512 will move move to ABCD_part3.xml
Fourth/remaining records 11512 will move to to ABCD_part4.xml

Please help on this .

SAX::PurePerl(3)					User Contributed Perl Documentation					  SAX::PurePerl(3)

NAME
XML::SAX::PurePerl - Pure Perl XML Parser with SAX2 interface SYNOPSIS
use XML::Handler::Foo; use XML::SAX::PurePerl; my $handler = XML::Handler::Foo->new(); my $parser = XML::SAX::PurePerl->new(Handler => $handler); $parser->parse_uri("myfile.xml"); DESCRIPTION
This module implements an XML parser in pure perl. It is written around the upcoming perl 5.8's unicode support and support for multiple document encodings (using the PerlIO layer), however it has been ported to work with ASCII/UTF8 documents under lower perl versions. The SAX2 API is described in detail at http://sourceforge.net/projects/perl-xml/, in the CVS archive, under libxml-perl/docs. Hopefully those documents will be in a better location soon. Please refer to the SAX2 documentation for how to use this module - it is merely a front end to SAX2, and implements nothing that is not in that spec (or at least tries not to - please email me if you find errors in this implementation). BUGS
XML::SAX::PurePerl is slow. Very slow. I suggest you use something else in fact. However it is great as a fallback parser for XML::SAX, where the user might not be able to install an XS based parser or C library. Currently lots, probably. At the moment the weakest area is parsing DOCTYPE declarations, though the code is in place to start doing this. Also parsing parameter entity references is causing me much confusion, since it's not exactly what I would call trivial, or well documented in the XML grammar. XML documents with internal subsets are likely to fail. I am however trying to work towards full conformance using the Oasis test suite. AUTHOR
