PATH.IGNORE_EMPTY_ELEMENTS 

This method ignores the empty elements in a list. 
For example, if the delimiter in a list is “,” the 
following list contains an empty element after the 
entry “a=10”:

a=10,b=11, ,c=89 

The element following b=11 contains a space and 
is not considered an empty element. 

Consider the following header: 

Cust_Header : 123,,24, ,15 

The following expression returns a value of 4 for 
this header:

http.req.header("Cust_Header").

typecast_list_t(','). ignore_empty_

elements.count 

The following expression returns a value of 5 for 
the same header:

http.req.header("Cust_Header").

typecast_list_t(',').
