I tried:

Assuming your context node is each row element in turn,

sum(total | preceding-sibling::row/total)

should work. (Short for sum(child::total | preceding-sibling::row/child::total) )

The "+" operation won't work for this since the second argument "preceding-sibling::total" isn't a number (even if it did return anything, it'd be a node set). To add the numerical values of nodes in a set you can use the sum() function.

More complex cases can be, um, "baroque".
