The DataDecorator action allows you to convert, calculate or transform just the data in results using one or more functions. You add functions to individual fields, as needed. With multiple functions, each is applied in order to the data for that field.
Note:  
This action does not change the structure of results, filter results or combine data in any way.
To transform result data
1. Connect document-type results from another block as input to DataDecorator.
The Block Properties for this action displays two panes with the structure of the input document and a pane with properties you can assign to the currently selected input field.
The input structure can contain:
* = a root or structure node that contains children but does not repeat. The root node completely wraps the entire input document.
* = a repeating node, usually with children.
* = a field (node) that contains data. If the node name begins with @ this is an XML attribute. Otherwise it is an XML element.
