Specifying a path for output mapping
In output parameters mapping you must specify a path for a mapping with response of type BODY.
If the response content type is application/json, you must specify a JSON Path. For more information on JSON Path syntax, see the Internet.
If the response content type is application/xml, you must specify an XPath. For a reference of the XPath syntax, see: http://www.w3schools.com/xml/xpath_syntax.asp.
When using a simple path that points to an element that is repeating, or is part of a structure that is repeating, the first occurrence is retrieved by default. To extract a different occurrence, you can use index and filter expressions. See the examples.
