I need to show in HTML a column of a table that shows the acummulated
quantity... If, for example, I have:
<row>
<total>1</total>

<row>
<total>2</total>
</row>
<row>
<total>3</total>
</row>
<row>
<total>4</total>
</row>
I want to show in HTML:
1
3
6
10
I tried:
total + preceding-sibling::total
but it didn't work.
Fun.
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".
Cheers,
Wendell
