root ==> demo
sublistlength --> 3
sub name 0 :: #text
sub name 1 :: empid
sub name 2 :: #text
root ==> demo
sublistlength --> 3
sub name 0 :: #text
sub name 1 :: empid
sub name 2 :: #text

I have only one chid but i got the number of child of rootelement as "3" due to whitespace character as shown in output(#text) but when i manually type XML Files in LINEAR fashion means i'm getting correct output .
