XPath/XQuery days-from-duration function

Summary

Returns the number of days in a duration.

Signature

fn:days-from-duration(
$arg as xs:duration?
) as xs:integer?

Properties

This function is deterministic, context-independent, and focus-independent.

Rules

If $arg is the empty sequence, the function returns the empty sequence.

Otherwise, the function returns an xs:integer representing the days component in the value of $arg. Given that a duration is a ($months, $seconds) tuple, the result is the value of ($seconds idiv 86400) .

If $arg is a negative duration then the result will be negative.

If $arg is an xs:yearMonthDuration the function returns 0.

Examples

The expression fn:days-from-duration(xs:dayTimeDuration("P3DT10H")) returns 3.

The expression fn:days-from-duration(xs:dayTimeDuration("P3DT55H")) returns 5.

The expression fn:days-from-duration(xs:yearMonthDuration("P3Y5M")) returns 0.
