A lot depends on how far you want to go. If you're prepared to split it at a
boundary between children of the body element, it's not too hard. If you
need to cater for deeply-nested tables, with the possibility of having 500K
of text in a single table cell, then it's much harder.

For the first case, it's a fairly simple exercise in sibling recursion:
write a template that processes the first child of <body>, and then calls
itself to process the next child (following-sibling::*[1]) and so on,
passing the accumulated text size as a parameter, and exiting when this
reaches some threshold.

(I say simple, but I use this as an exercise on XSLT courses and some people
find it very difficult, if they're not used to recursive list processing).
