remove last entered node()
This function can be used to remove the last instance of a entered node a during the construction of the target tree. See example for details.
The function cannot be used on node a itself.
The return value of the function in case of success is true. If an incorrect node name is specified, an error will occur.

a |
The name of the node. If nothing is specified, the parent node is used. |
Example
Let's assume that in the mapping the node some_node is created once in the target tree and in a loop the node loop_node is created four times.
On field remove, in the second iteration of the loop, we execute the function described here, with the value loop_node for parameter a. Alternatively, we could choose to remove node some_node here.
However, we could not execute the function on node loop_node itself.
