Extracting Results from an Array Variable
If a service returns an array variable—such as a String list, a String table, or a document list—to a DSP, you use the %loop% tag with a variableName to extract values from the elements in the array.
When you use %loop% on a document variable, the scope within the loop block automatically changes to encompass just those elements within the specified document.
The following example shows a loop that extracts values from a document list (called items) that is returned by the service named orders:getOrderInfo.
For additional information about the
%loop% tag, see the
%loop% tag description on
%loop%.
