Return value



The name of the query can be used as a variable in the following action properties:

The following code example strings show two name-value pairs that can be used in a name-value collection. The values returned by the XPath queries can replace variables in an action property. The values are referenced by name, with $(user) and $(machine), in the action property. For example, if the $(user) and $(machine) variables are used in the MessageBody property of IShowMessageAction, then the value of the XPath queries will replace the variables in the string.

name: user
value: Event/UserData/SubjectUserName

name: machine
value: Event/UserData/MachineName
