I have an XML document (A.xml) and it is being transformed to another XML document (B.xml), which is nothing but a replica of A.xml with an unique @id being added to each element belonging to B.xml. And this part is done.
Now I would like implement a mechanism which would track character count of every text node within B.xml (within a temporary tree) and based on maximum character count, the mechanism would be able to split and serialize B.xml in one or several parts.
Source XML Document (A.xml):
<?xml version="1.0" encoding="UTF-8"?>
<root>
<!--
Rules for splitting:
1. ?head/text()? is common for all splits.
2. split files can have 600 characters max each.
3. ?title? elements could not be the last element of the any result document.
-->
<head><!-- 8 characters -->Kinesics</head>
<section>
<para><!-- 37 characters -->From Wikipedia, the free encyclopedia</para>
<para><!-- 204 characters [space normalized]-->Kinesics is the interpretation of body
language such as facial expressions and gestures — or, more formally, non-verbal
behavior related to movement, either of any part of the body or the body as a
whole. </para>
<section>
<title><!-- 19 characters -->Birdwhistell's work</title>
<para><!-- 432 characters [space normalized]-->The term was first used (in 1952) by Ray
Birdwhistell, an anthropologist who wished to study how people communicate through
posture, gesture, stance, and movement. Part of Birdwhistell's work involved making
film of people in social situations and analyzing them to show different levels of
communication not clearly seen otherwise. The study was joined by several other
anthropologists, including Margaret Mead and Gregory Bateson.</para>
<para><!-- 453 characters [space normalized]--> Drawing heavily on descriptive
linguistics, Birdwhistell argued that all movements of the body have meaning (i.e.
are not accidental), and that these non-verbal forms of language (or paralanguage)
have a grammar that can be analyzed in similar terms to spoken language. Thus, a
"kineme" is "similar to a phoneme because it consists of a group of movements which
are not identical, but which may be used interchangeably without affecting social
meaning".</para>
</section>
<section>
<title><!-- 19 characters -->Modern applications</title>
<para><!-- 390 characters [space normalized]-->Kinesics are an important part of
non-verbal communication behavior. The movement of the body, or separate parts,
conveys many specific meanings and the interpretations may be culture bound. As many
movements are carried out at a subconscious or at least a low-awareness level,
kinesic movements carry a significant risk of being misinterpreted in an
intercultural communications situation.</para>

My input XML contains 1562 characters (assuming s+ is equal to A.xml into 4 parts using the rule mentioned within source xml document.
Does anyone have any idea how to do this? Any ideas or comments are greatly appreciated.

Details on Split procedure:
Contents of element ?head? should part of each and every XML file.
Files could be splitted from middle of section but not in the middle of a paragraph.
Not ?title? element should come at the end of an split.
Maximum number characters (excluding opening and closing tags) in a split file is upto 600.
