You can add variables in the XMap editor. You can map values to variables and use the variables in predicates or as temporary holders for values. You can map variables to output elements.
When you create a variable, it appears in the input and the output schemas in the XMap view. The Developer tool adds a dollar sign ($) to the variable name to indicate that it is a variable.
You can create a variable that is a list of multiple values. You can use a list variable for the same purpose as a multiple-occurring schema element. Configure a list variable as input for a repeating group or configure a predicate to search for a value in the list variable.
For example, you have an XML document that contains addresses. You need to create a list of all the countries from the addresses. Map the country element into a $countries variable that you define as a list.
