  Explanation

  Points to remember:

  *

  XML must have a root element.

  *

  XML only allows one root element

  *

  To avoid multiple root issues, you must create a root element for the XML output, whenever we transform output

  *

  When mapping array elements (JSON or JAVA) to XML, wrap the map operations in {(..)} -{ } are defining the object

  ( ) are transforming each element in the array as a key/value pair

  *

  The transformation to XML would fail if the above mentioned considerations were not taken into account.

  *

  Thus the transformation script declares a root element as trains and wraps the data in "{( )}".

  Whenever you see such type of question, always look out for root element followed by {( )} wrapping map.

  I call this a "Wrap The Map" scenario. Hope it would help you remember !
