Kent> I have some duration elements like <alltimes>
Kent> <tduration>PT1H23M</tduration> <tduration>PT5M</tduration>
Kent> <tduration>PT44M12S</tduration>
Kent> <tduration>PT57M23S</tduration> ... </alltimes>
Kent> What is the most efficient way to sum the durations? Is
Kent> there an xpath = expression for this?
Yes. If you are using XPath 2.0.
You should use the sum() function.
But first you need some duration values - at present, all you have are
string literals - untyped text nodes.
Colin, you're right, on the assumption that there's no schema and that the
transformation isn't schema-aware. If there's a schema that describes these
elements as being of type xdt:dayTimeDuration, and if you use a schema-aware
processor, then you can just sum them directly: sum(tduration).
