XPath Constraint Functions
Last modified: March 12, 2026
The following pages describe the functions that can be executed within constraints:
- true
- false
- not
- length
- string-length
- year-from-dateTime
- month-from-dateTime
- day-from-dateTime
- hours-from-dateTime
- minutes-from-dateTime
- seconds-from-dateTime
- quarter-from-dateTime
- day-of-year-from-dateTime
- week-from-dateTime
- weekday-from-dateTime
- contains
- starts-with
- ends-with
In all these functions, the attribute in the example is just the name of the attribute, for example
Name. This is for clarity. However, the attribute can also contain the path to the attribute, for example Sales.Order_Customer/Sales.Customer/Name.
