Boolean

The Boolean menu contains the following functions:

• Logical And: If both arguments are true, then the function returns true. If either argument is false, then the function returns false.

• Logical Or: If either argument is true, then the function returns true. If both arguments are false, then the function returns false.

• Logical Not: If the argument is false, then the function returns true. If the argument is true, then the function returns false.

• Language: Returns true or false depending on whether the language of the context node is the same as or is a sublanguage of the language specified in the argument.

• Logical False: Returns false.

• Logical True: Returns true.

• Boolean: Converts the argument to a boolean. For detailed information about the logic, see the XPath 1.0 specification.
