In the process definition example above, the "taskExport" task includes a Procedure.If element which has a conditional Expression attribute. If this expression evaluates to True, then all of the Procedure.If element's child elements will execute. If the expression is False, then processing will continue with the next element following the Procedure.If element's child elements. So, as shown above, if the "doExport" Request parameter equals 1, then the yellow-highlighted elements will execute; otherwise they'll be skipped.
Several other elements are available for use in controlling conditional branching:
Procedure.Else - This element must be a sibling of, and immediately follow, a Procedure.If element. It identifies a conditional block of procedures that will be run if the Procedure.If element immediately above it evaluates to False. If the Else block ran, the token @Procedure.myProcedureID.rdReturnValue~ returns True, otherwise it returns False.
Procedure.Switch - This element works with one or more child
Procedure.Switch Case elements to define conditional blocks of
procedures to be run when a specified value matches. Use it when there are
multiple conditional blocks defined and just one of them is to be run,
based on the value of a variable. You can also use a child
Procedure.Switch Else element, which runs its block of procedures
if none of the previous Switch Case elements match the specified
The value to test against is specified in the Expression attribute and can
The Data Type attribute ensures comparisons, especially of dates, are made
