Merging schema xml with data xml with Java

[bonjo]

Well, I didnt do much, just used System.nanoTime () to measure the difference.
so I did:

sum = 0;

and repeated 1000 times:

startTime = System.nanoTime();
**operation**
endTime = System.nanoTime();
sum += (endTime - startTime)/1e9;

and at the end, the average time is

sum/1000
