I am on version 6.1 of WMB.

Is there a function that can return you the index of a repeating XML field?

Example

<A>
123
abc
567
837
</A>

I want to be able to know the index value of element 567 which in this case is 3.

I know that I can create my own loop and iterate and increment my own index, but I was wondering if there was a function, similar like POSITION works for string, this would return the index of a tree element.

No.

Why do you need to know this? What benefit is the index position of the element to your requirement? Given that having found the element in the tree, you can always go back to it without knowing the index value.

You should always code using references, and never code using indexes.
