Hi Simon,
Though there could some other smarter solution,I have used the following approach to solve this problem.

Assuming we have the contents of the file /tmp/MyNewArticleFile.rtf as ,

cat /tmp/MyNewArticleFile.rtf

HTML Code:

Times of India
Edition-1
Date:27 th May

Document 1 of 20

All blah blah goes here

Blah

Document 2 of 20

All blah blah goes here

Document 3 of 20

Document 4 of 20

I have written the following script that process the above file to generate the output.
Here the assumption is the Document has 20 Pages.

Code:

#!/bin/ksh
let page=1
while [[ page -le 20 ]] ; do
sed -n /Document\ $page/,/==========*/p /tmp/MyNewArticleFile.rtf > /tmp/ArticleSplitPage-$page
((page=page+1))
done

Upon execution of the above script i get 20 pages spilt according to the Document no.

cat /tmp/ArticleSpiltPage-1

HTML Code:

Document 1 of 20

All blah blah goes here
Ad Page
Blah

================================

Thanks,
Nagarajan Ganesan.

ppi::document::fragment

PPI::Document::Fragment(3)				User Contributed Perl Documentation				PPI::Document::Fragment(3)

NAME

       PPI::Document::Fragment - A fragment of a Perl Document

DESCRIPTION

       In some situations you might want to work with a fragment of a larger document. "PPI::Document::Fragment" is a class intended for this
       purpose.  It is functionally almost identical to a normal PPI::Document, except that it is not possible to get line/column positions for
       the elements within it, and it does not represent a scope.

METHODS

   index_locations
       Unlike when called on a PPI::Document object, you should not be attempting to find locations of things within a PPI::Document::Fragment,
       and thus any call to the "index_locations" will print a warning and return "undef" instead of attempting to index the locations of the
       Elements.

TO DO

       Integrate this into the rest of PPI so it has actual practical uses. The most obvious would be to implement arbitrary cut/copy/paste more
       easily.

SUPPORT

       See the support section in the main module.
