This could be encapsulated as a page "grammar" which would be parsed to recognize the structure. The parse might be ambiguous... in which case there would need to be a heuristic, e.g. a weighting function, to select the best fit. Time to dust off the old AI textbooks (or buy new ones...). This is a _very_ interesting research problem. Len -- Leonard R.
