Given an xs:duration value,
returns the number of hours in that duration.
Syntax
xs:integer?hours-from-duration(xs:duration?)
Inputs
An xs:duration.
Output
An xs:integer
representing the hours component of the given xs:duration. Be aware that for an
xs:yearMonthDuration, this
function always returns 0
because there is no hours component of an xs:yearMonthDuration. Also, if the input
argument is the empty sequence, this function returns the empty
sequence.
