Hello,

Here is my XML:

</primaryErrorPts>


here is what I want to do:
loop through the "errorPt"s, from each "errorPt" I want to pick first the first "antiCollisionData". Then loop again to pick the second "antiCollisionData" from each "errorPt" and so on....
How can I do that especially that the number of "antiCollisionData" nodes will not always be 3.

Any ideas?


Thanx
