NODES – Return the number of nodes in a string

This function returns the number of nodes within a string, using a specified delimiter.

NODE(<string>,<delimiter>)
Where:
<string>
String from which to extract the data.
<delimiter>
String that delimits each node.
Unlike the functions WORD and WORDX, which ignore leading and double spaces, the NODES function counts every delimiter. For example, the following command returns 5: 
NODES(“FIVE!FOUR!THREE!TWO!ONE”,”!”,2)
The following command returns 6: 
NODES(“.A.B..C.D”,”.”,2)
