choose()

XSLT/XPath Reference: XSLT elements, EXSLT functions, XPath functions, XPath axes

The choose function returns one of the specified objects based on a boolean parameter.

Note: This method should be used instead of if(), which has been deprecated.

choose( boolean , object1, object2 )

boolean: The boolean operation to use when determining which object to return.
object1: The first object to consider returning.
object2: The second object to consider returning.

If the boolean parameter is true, the first object is returned; otherwise, the second object is returned.

Note: All parameters are evaluated, even the one that's not returned.
