(D) is correct:
Can you test: /purchaseOrder//comment[not(following::description) ] in webpage page: http://www.xpathtester.com/xpath
D is correct.
Yes D is Correct.
Correct is D not(following: : description)… easy to test and confirm.
item[0] is incorrect index (index of first element is 1)
B is correct the indexing of number starts with 0, if there are n numbers indexing will be till n-1 elements.
did you actually test item[0] and got an element as responce?!
can you please provide me with example and tell me which IE did you use?
