The following operators can be used in XPath query constraints, both in the Modeler and in Java code:

Operator Description Example Return value
= Equal to price = 9.80 true if price is 9.80, false if price is 9.90
!= Not equal to price != 9.80 true if price is 9.90, false if price is 9.80
< Less than price < 9.80 true if price is 9.70, false if price is 9.80
<= Less than or equal to price <= 9.80 true if price is 9.80, false if price is 9.90
> Greater than price > 9.80 true if price is 9.90, false if price is 9.80
>= Greater than or equal to price >= 9.80 true if price is 9.80, false if price is 9.70
or Or price = 9.80 or price = 9.70 true if price is 9.80, false if price is 9.60
and And price = 9.80 and amount = 1 true if price is 9.80 and amount is 1, false if price is 9.70 and amount is 1, false if price is 9.80 and amount is 2, false if price is 9.70 and amount is 2

Additionally, the following operators are supported in Java code only:

+ Addition 6 + 4 10
- Subtraction 6 - 4 2
