xml - How to grab element by index when elements have different parents -

-

this question has answer here:

i trying grab elements of index 3 , 4 in following xml:

<automated>     <group>         <test><id>testid</id>...</test>         <test>...</test>         <test>...</test> <!-- 3? -->     </group>     <test>...</test> <!-- 4? --> </automated>

as far aware, expression //x used grab elements type x. expression attempting use grab 3rd , 4th elements is:

//test[3] , //test[4]

however, element //test[4] not return anything. upon further investigating, i've realized //test[1] return both elements 1 , 4. first child of first element, , second (first test?) child.

is there way achieve want do?

the other thing can think of (since i'm using in c# , have access scripting this) using counter iterate through possible selections of //test[x] , index myself. however, seems more work necessary.

as turns out, 1 can use parentheses fix issue, xpath use precedence. 

(//test)[4]

will give me fourth element of test elements in xml document, whereas

//test[4]

does not exist in document, there no element 4 total test children.
