An operator that returns the number of subelements of the given element that have occurred thus far in processing.
If an element qualifier is not given, children returns the number of subelements of the current element. If it is used before the current element is processed, it will return zero (0).
If an element qualifer was given, the count of the children processed so far of the indicated element is returned, including the currently open child. Inclusions are counted, as well as proper subelements.
