in reply to section nesting

What defines "improper" nesting? Your example suggests no nesting is allowed at all. Is that the case? Anyway, I'd use a single tokenizer and a counter. Whenever you see a <sec id = "..."> token, increment the counter. Whenever you see a </sec> token, decrement the counter. Whenver the counter has a value unequal to either 0 or 1, you have "improper nesting" - that is, assuming no nesting at all can happen.

[Corion]: Hmmm. I feel a Meditation coming on. I wrote a module, DBIx::PivotQuery, which returns a table-like set of rows (AoA) but some columns are generated from column values, like in an (Excel) pivot table or a ROLLUP command
[Corion]: My current approach for subtotals involves rerunning the given query, with the hint to the user that they should use a temporary table if they want better performance.
[Corion]: But I could create that temporary table in the module and use it for the improved perfomance directly instead.
