functx:min-string

The minimum of a sequence of values, treating them like strings

Description

The functx:min-string function returns the minimum of the values in $strings. It differs from the built-in fn:min function only in treats values of all types like strings. The fn:min function, by contrast, treats untyped and numeric values like numbers (and an error is raised if they are not numbers).
